Hi, on my last two flights i´ve had an issue. The FMC freezes, but this ONLY happens during the cruize phase. It freezes showing the legs page, and no matter how many times i press a button on the FMC, it doesn´t respond. Thanks in advance for your help!

Hi, this i my first post in this forum and before i describe my problem i want to excuse my english i am from Germany and i am still learning ;)So when i and a friend make our Multicrew session, everything in the cockpit is synced until we begin to taxi.So, when we taxi (also happens while we are in the air) and the PF turns the plane to the right everything is correct and the heading is the same of PF and PNF.But when he turns left and passes the 180° mark, the PNF heading freezes at 182°.At PF side everything is still turning and the cockpit is also synced.And also the PNF plane is still moving but is stuck at this 182° degree.The Navigation Display of the PNF is also still showing the correct heading, only the plane itself is stuck.After the PF passes the 360° mark, the PNF's plane is back turning, but only until he passes the 180° again. Or he turns right and passes 180°, the PNF's plane is back turning and if he continue turning right everything is working at the PNF's side, just at a left turn there exists this problem.This problem exists if we try a FS9-FSX but also at a FSX-FSX connection.We both have W7 64bit and have the Fokker SP2.5 installed.Do you have the same problem ?ThanksMichael

Hello, I have been having long pauses and freezes with the 777 from day one and have not had the chance to do a whole flight as this issue was driving me crazy. Well, someone asked me to try and deactivate the FSUIPC autosave and try it. I just completed two short flights (EDDF-EGLL and back) and had ZERO pauses or freezes of any kind. The flights were amazing. I am going to try a long haul flight and see how that one goes. Will report tomorrow. It looks like in my case, the problem was with the FSUIPC settings. Not sure if anyone esle can get their pause/freeze issues corrected by doing this but it worked for me. Thank you McLaren and B247NG for your suggestions. Now, Let's Go Flying!!!!!

A lot of individuals have placed the Uiautomationcore.dll into their main fsx folder (Vista Version) to avoid FSX Menu crashes. I just found out that some fsx software addon is installing the wrong version of the Uiautomationcore.dll into the main fsx folder along with their product. I discovered the wrong version as I once did not believe in placing the Uiautomationcore.dll into the fsx directory as I thought it causes other anomalies. It supposedly only fixed FSX Menu crashes/freezes but others have stated it fixes all crashes. I have kept this dll out of my main fsx directory as I didn't believe in this fix but this weekend I had a ntdll crash and ran the AppCrashView program and discovered that the Uiautomationcore.dll was in my main FSX directory!!! Now who put it there!!! (not saying but I saw in the PMDG 777 Intro guide that they recommend this dll in all installations and provide a link to the WRONG version). The version I found was 6.0.6001.18000 and that's the wrong version. The correct version is 6.0.5840.16386. If you do not remove the dll or use the wrong version, you will get a freeze, an apphang, or ctd. The correct version is located in the AVSIM Software and Hardware Guide - http://forum.avsim.n...-software-guide. Click on the latest version of the guide. Goto Page 17. Once you download the version you will have to rename it to Uiautomationcore.dll and then drop it in your Main FSX folder. You can check to see what version is installed by right clicking on the dll and then selecting Properties. Then look at the Details tab. If you have to 6.0.6001.18000 version you need to remove it immediately. I'm still not positive that this dll (the correct version) will fix all of your crashes, problems with the PMDG 777, 737NGX, the FSDT Addon Manager, etc., etc., but it might. I have tested the correct version and no longer get an ntdll crash. And, according to Zeljko (B247NG), it eliminated freezing, stutters, and CTD's and the FSX Menu was more responsive and there were fewer stutters in the PMDG 777 and everything was smoother while running FSX. In my testing, I definitely saw most of my stutters go away and things seemed much smoother during flight. In case anyone is unaware, the uiautomationcore fix is only for Windows 7, 64 bit users. If you have Windows 8 installed, it is not compatible and you will see problems if it is installed. I think this is a fix for a lot of our problems.... Best regards, Jim

Hey all, my name is Joseph and im having an annoying issue with the 747. please note that this does not occur with the 777, even when i switch to it immediately when this occurs. now, i select my 747, usually air canada livery but i tried with all of the, it opens slowly, then it initializes and right when it hits zero it freezes completely, but im able to switch a/c. i havent had this issue before and it is really bugging me because i love to fly it. HELP!!!!!!!!!!!!!!

Hi guys, first post here so I have had FSX for ages now and finally got a decent system to run it on, An HP Computer with an AMD Phenom ii x4 965 processor at 2.9 GHz, 3 GB RAM, A AMD HD Sapphire 7750 GDDR5 1GB graphics card and 500GB memory space, however mid flight when playing FSX just freezes i.e. the display stops moving, the sound continues yet the flight panels freeze as well as the aircraft itself. About 10 minutes later it unfreezes but the process repeats randomly I am really really frustrated now, I have tried everything! I got rid of the uiautomationcore.dll and tried the FSX CFG enhancer and played around with my FPS and graphics card settings, bearing in mind the card is only new! There are no problems with overheating either i checked that out. Please Please help me resolve this problem, I just want it to work enabling me to complete a flight! Thanks

Hello all! I'm having a strange problem in Prepar3D v 4.1: everytime I use right mouse click to turn a knob or flick a switch, the simulator stops and freezes for a few seconds. Then the screen flickers, the switch or knob changes position and the right mouse button menu opens. It started after upgrading to 4.1. I'm using 60 Hz refresh rate, unlimited frames and vertical sync. Video card is NVidia 1070 GTX.

Just wondering if anyone else has seen a long (2-3 second pause) at FSDT KORD and if there is a solution? It ONLY happens at night in my PMDG 777-300ER. I went to FlightBeam's KIAD and the issue was not there. Just at KORD. My Gate was B22. I have not tried it at any other gate at KORD but believe it will occur there too as it happens as I taxi to the takeoff runway too. Very annoying. Looks like it coincides with night lighting that flashes. Thanks for any assistance. Best regards,

Hi guys, im having a problem when using this aircraft. when i want to change from full screen view to a different one, fsx freezes, or the image starts flashing. it also happens when i use time acceleration. example: accidentally i select 8X and when i return to 4X or normal speed the problem happens. i hate when this happens especially when i am on approach and so close to land, because it keeps me from contiung with my flight. im desperate, please help me. thanks in advance, tatin 98
