hi, I use OpenFlipper1.0, and when I launch OpenFlipper.exe, it complains: Warning! The OpenGL capabilities of your current machine/driver are not suffient! The following checks failed: OpenGL version less then 2.0! Please update your driver or graphics card. When I press "OK", it pop out a crash windows which says "Stereo Setting:OpenFlipper.exe". My evironment is windowsXP, Winfast GTX460(NVidia), and I have already upate the driver from nvidia official set. Is this a bug? or could you tell me how to deal with this problem? Regards yaoyansi
