Not sure if "Performance" section is the right place for this, but it seems to be the best fit.

I have two workstations, both running Windows 7 x64 and Solidworks 2011. Both of these PC's are experiencing this issue. The software works as it should, until you save, or close a file. With these two, Solidworks hangs, or freezes. Now I have let them sit for upwards of an hour, and no change. At that point Windows asks to close the program, and generates a crash report which is always just a vague APPCRASH. The three other workstations in the office do not have this issue. Everyone has Windows 7 x64, and SW 2011. All the hardware specs on these particular machines exceeds the requirements needed to run perfectly. So I am at a loss.....any ideas?
