Trouble with Vista

Two major platforms for my PPCam project is Windows XP and Windows Vista, I believe I hit the problem on Vista.

I don’t think it is my code problem, but I just cannot, so far, get a workaround. The problem is WM_SYSCOMMAND of SC_MOVE with HTCLIENT does not work, it seems some coordination translation got problem.

I suspect it is Creative’s driver problem, since I’ve tested this webcam on Windows XP without any problem, and another Logictech webcam on Windows Vista is running just fine. I need to do some more research to figure out what’s the problem, and find out what’s the workaround.
