I have recently installed proe 4 student edition on new dell w/vista. I seem to be having problems w/ dim. lines showing up, and, the curser highlighting any lines, datums, or points picked to place dim. The same version at school works, so trying to do homework and practice is most frustrating. I've been told to be sure that the graphics driver is most up-to-date, which after checking with intel, it is. Any thoughts and comments to help are much appreciated
