Hi guys, i'm using parallels desktop 7 now to run win 7 with Solidworks 2010 SP 5.0. I'm having problem when trying to save a file. When i were to save a file, i will receive a message the handle is invalid. So actually what does it mean? I only will receive this message occasionally. Does any one have clue on what is actually happens? I was using VMware Fusion 3 previously and just transfer to parallel desktop 7 recently.
