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

Just a guess, not much info to go on, but it's good practice to use ATL::CString instead of WTL::CString.

So, change:
#define _WTL_USE_CSTRING
to
#define _WTL_NO_CSTRING
#include <atlstr.h>

(I think that _WTL_NO_CSTRING is only needed if you are including atlmisc.h, not 100% sure without checking)
