The problem we have is actually with the MS V8.1 vesion but this forum was the closest so I am posting it here.
The graphics are very slow on one of the PC's. In some cases it dissapears completely. we use the option Graphic Acceleration in the Render View Attributes dialog box but that does not always solve the problem.
So far the only fix is to go out of a drawing and come back in, but that is very time consuming.
So just to make sure of some details... do you have other PCs/workstations where the same file displays okay? If so, is there anything different on the systems (e.g. free disk space, graphics subsystems, driver versions, video memory, etc.)?
