>> Is this with Win 95 or are you running Win 3.1?? Next, try setting your video driver to a standard window driver as apposed to a 3rd party video driver that may have come with your machine.. If this solves it, then maybe you need to check and see if there are newer video drivers for your machine..

Sylvain, I know about the 3.0b version of VFP, but I can't find that. Even in Microsoft Distributors i found that. Do you know if I can found something like a upgrade to the 3.0a version or a patch file, maybe ? A friend tell me about the same problem wich occur with him, and the problem solution was the change to 3.0b.
