Hi,The aircraft is running pretty well with me, but two things I've noticed, which I haven't seen mentioned here - 1. The clickable buttons on the FMC often don't match what appears on the screen. I have to click at precise points on the FMC buttons, otherwise an adjacent number will appear instead. Eg. clicking in the middle of the zero key will produce an eight. Same goes for numerous other keys, but only on the FMC it seems.2. Most importantly. Ever since installing the 800 I have had the following crash to desktop problem:Flying an -800 VC Scandinavian Star livery. Flight progresses as usual, but after a certain length of time, typically when switching views, the screen will black and then drop to desktop with an error message saying I have run out of memory and windows needs to expand the virtual memory available...followed by loads of HDD accessing.I have a Dell Inspiron 8600, 1.5 centrino, with 512mb ram, 1920x1200 resolution screen, running XP. I have atleast 15gb of HDD space left and I would have thought that 512mb of RAM would be enough. Apaprently not, although I never had a problem with this before on the 700. It seems to be something particular to the new aircraft.Is there a "memory leak" somewhere? Anyone else had this problem, or am I all alone here? Dave

Dave1. Have you resized the FMC chaning the numbers in the panel.cfg?2. Sounds like you have the swap file size set to a specific, too small amount. Change it and let Windows handle the swap file size. 512Mb RAM is borderline for this addon specially as you are running at a very high resolution. With any NG and at Simflyers CYYZ I easily get up to approx 600-700 Mb used RAM. ANd that will use the swap file. If you have a lot of other programs running it can easily saturate the swap file. Check in the Task Manager.Hope it helps,

Do you know that you can actually type with the keyboard anything you want to put on the FMC?Chekout the manual.

Cheers for the reply,No, I haven't made any changes to the panel. This is all from a fresh install of the NG and a fresh install of FS9 even. It's not a big issue, but it does seem odd. Specific to the new addon.I will have to look into the swap file size. It always seems like the court is out on the subject of extra RAM, but it does seem to be a RAM issue that is slowing me down. Panning the virtual cockpit or even the 2D cockpit causes pauses, and blank panel patches, as the HDD spins - it seems like virtual memory is being used from word go. I do have a 1MB graphics card though so I thought that might help.Will increase the swap file, but it might be a reason to bankrupt myself on another 512 RAM. Seems a shame as everything else runs fine on what I've got.Dave

I do use the keypad sometimes but just find myself preferring to click the keys instead.Dave

for the "memory leak"... Check you don't have a scenery with an empty "textures" directory. Bye, Luca

I remember something about saved situation files. If you had a saved situation file from before the 800/900 upgrade, and then used it after the upgrade it can possibly cause this problem. THe FMC was resized a bit bewteen these two releases. Try to start out in a clean saved flight with a default plane and change it to a PMDG NG and see if this will cure your FMC probs.Hope it helps,

Hi Dave.In addition to resize the window, you could try another screen resolution. I noticed the clickspot for 0 is a little bit skewed in 1024 windowed mode. It works perfect in fullscreen 1280 and 1600 though.
