... and it is supposed to support Vista. My computer runs Vista and sometimes ProE takes forever to repaint. The problem is the other ProE workstations are running XP and our usual practice is to keep us all on the same datecode as we have had probs before reading files with different datecodes. So should we all update to M090 - IOW does it work on XP too? Or if I am the only one to go to M090 could we have trouble filesharing?
