Bruno;

I do not want to lead you in the wrong direction but it is nice to have as much information as possible. If you can make your application work on a similar computer then you know it is a problem specific to your set up. Several people are using the same video card successfully, which is good news. If possible compare which motherboard, BIOS and version number are being used. You have to reduce the number of variables one at a time. Try the easy things first.

In the days of FoxPro (before VFP) George Goley said, “One computer in 500 will not work with FoxPro no matter what you do”! Perhaps things have improved with VFP and newer hardware? :)
