I have FS9 installed on my system and I can not run the program in windowed mode only full screen mode.If I run in windowed mode I can not change views and no pop up panels will work.This is only in windowed mode, in full screen everything works fine but running in full screen is a drain on my system. I was hoping someone might have a clue as what could be going on?My specs are below and I will try and attach a pic of Nivida Inspector driver screen as these are the latest video drivers.

I think there is a better way, but I've forgotten it. What I do remember is try using the Windows Classic theme in Vista.Hope this helps,

Have no idea how to do that. JeffG

Why is it such a drain for your system? The CPU seems pritty well, just try it to overclock and see how the things change.You should have a programm called "AMD Overdrive" shipped with your things, if not search for it. ´This prohramm will help you to overclock your system. But do this only if you have a good cooler installed, otherwise the CPU might get a little bit hot.I hope I could help you a bit.

I have never used Vista, but in Win7 I need to right click the FS9.exe file and select "disable desktop composition" and "disable visual themes". The windows active desktop can interfere with fs9 otherwise.Hope this helps.Peter

I will try that and see what happens,Thanks Jeffg

HelloI notice in your specs you have FSX ,but I don't see FS9. Are you talking about FSX? ,If not then I can see no reason why your PC should struggle with FS9 .My PC is about six years old, single P4 2.8 ,1gB ram plus GForce GT6600 Gcard.It runs FS9 very satisfactorily no problems in full screen OR windowed (if I wanted to.)Look at your specs there vastly better than mine.If it is FSX you are talking about then it seems that only a few fortunate simmers can run that well ,however up-to-date their PCs are . I may be wrong but I don't reckon you need to be messing about with overclocking (particularly If it is FS9 you are talking about.cheers Andy.
