I am using the datagridview in an application. I am testing with a user. When I log into the PC the datagridview works perfectly, but when the user logins to the PC the datagridview does not redraw itself. Only the 1st column heading is drawn partially the rest of the datagridview is gray unless you select row in the grid then each row draws itself but if you place another app or window on top of it the windows image remains drawn over the datagridview until I select rows on the grid then they draw themselves one at a time as they are selected. The grid never works properly.

I log the user off and me on it work perfect again. We are both local administrators on windows XP sp2 I am a domain admin and the user is just a domain user???? What could cause this. It happens on several PC with several different users the same problem. It does not happen on one PC. This PC is the original test pc and has had Visual Studio installed on it but none of the affected PC have ever had VS installed. I just cannot get around this problem. All PC have every windows update installed and the System.Windows.Form dll is the same version in .NET framework directory.
