Hi,Well, I reinstalled everything. The past 24 hours during the reinstall were brutal. I think I may have isolated the problem. Can someone try this and see if its just my problem or a problem with FS2004. Let me know what video card and drivers you have as well.1. Start FS2004 in widowed mode and change to full screen mode at the Create A Flight screen. Then create a flight to anywhere, with any aircraft, at anytime. Once FS2004 loads, try going from full screen to windowed mode. Make sure you click outside FS2004 so its

i can't help, i can't get fs9 to work on my machine at all, and i have a cracked disk 4might help, if you said what kind of card you have. if you ati, no point in nvidia card owners trying your testsand i guess you didn't see my earlier post on your other post.install 1 thing, test. install the next thing, test. keep installing until it breaks. then you know what it is.might be worth install fs9 into a new directory, and see what happens in your three tests. no point in have 40+gb of addons to test basic functionality. if vanilla fs9 fails, no need to install the add ons until it is resolvedjd

Hi JD,Its not the add-ons. This problem happens with FS2004 with just the Service Patch 1 installed.

good, at least we have eliminated that. i thought you said you loaded everything back, and the behavior was still happening.what video cardwhat oswhat os service packdo you have DEP enabled?what antivirus, spyware, etc?those are the usual culprits.

Hi JD,Everything is loaded back. I tested FS2004 once the service patch was installed.Video Card: Nvidia 8800 GTXOS: Windows XPService Pack: SP2do you have DEP enabled?: What is DEP?Antivirus, Spyware: Zone Alarm, turned on or off same problem

data execution protection. new processors have it and i can't remember whether xp had it. i don't think so. it won't allow "data" memory to be executed.is there anything in the event log about fs crashing or becoming unresponsive?you're not overclocking anything, are you?all of your memory dimms are the same speed?, paired correctly?

It's under systems properties in the advanced performance section! Make sure it is set for essential window programs and services only.

Hi JD,I'm not overclocking. My memory: 4-Gig Corsair XMS2 DOMINATOR Twin2X2048-9136C5D. Memory is setup correctly.DEP is set as follows: Turn on DEP for essential Windows programs and services only.

any events in the event logs at time of failure? system, app, security? rare that things die without sending up a signjd

Hi Mike,I tried your scenario 1 and had no lock ups. I assume your lock up was immediate after returning focus to FS? I am running Vista Ultimate (32 bit) with the nVidia 8800 GTS card and the 158.24 drivers.My normal procedure is to start FS in windowed mode and get my flight set up and started. I then start up WideFS, and let my weather load from ASV. I then switch over to full screen mode. I have not had any lock up issues.
