Re: CFileDialog crash on Vista

My guess is it has something to with the Vista window renderer (http://msdn.microsoft.com/en-us/library/aa969540(VS.85).aspx). It is far more memory intensive. Normally you would not see an issue, but some boxes uses chip sets that use main memory for video memory. 

You could try turning of compositing, under the performance settings. Better yet set the performance settings to "performance". Windows 7 has add some performance increases in this area.

Might be worth a try.

I have been googling the problem and it turns out that the CFileDialog are handled differently under Vista, but I could not really find a solution to the problem. Does anyone have a hunch what could cause this problem? Do I need some special entry in stdafx.h or use a particular compiler flag? This is what my stdafx.h looks like
