We both have the same resolution High Color (16 bit) 800 x 600, but I have lots of problems today. Help for VFP isn't shown properly (e.g. I see dots and blanks there) and there are couple of other strange effects on my forms...

I set it to High Color (16 bit) in order to see UT properly. I can set it to 256 colors back, but I guess, I just have a wrong driver, so the correct driver should fix the problem.

My colleague has the same machine as I have and she doesn't have problems with this resolution...
