Hello,My FS2004 has gone off the rails a bit recently.It seems that whenever I start a flight and then press 'Alt+Enter' simultaneously to minimize FS2004 and start up AISeparation and ActiveSky, it crashes and I get the extremely annoying 'Microsoft Flight Simulator has Stopped Working' message before I can do anything else.I am running FS2004 9.1 with Windows Vista Service pack 2. It may help to note that I have recently installed the 'CaptainSim 757-200 2.2 Update.'Any help would be greatly appreciated.Regards.

It happens to me sometimes also. Not sure why it even happens. I tend to run my FS9 in windowed mode to begin with since I use synergy to go back and forth between 2 PCs w/ 2 monitors. In fullscreen it would always close FS when i moved to the second monitor. Anyway, my window would sometimes freeze, but the game is still running and I have to ALT-Enter to fullscreen for it to sync back up.....what is that about?
