I have an HP EliteBook 8540w. SolidWorks has worked fine for a couple years, but now it freezes after rotating the part. The part will rotate freely and continuously with no problem until the rotation stops. Then the beach ball comes up and I can wait up to 28 seconds before I can do anything. I ad contacted a SW AE, with no resolution.

SW 2013 SP5. NVidia Quadro FX 880M Windows 7 X64.

It is easy for SW Support to blame the computer, but all Memory tests show no problems. I am worried about the suggestion of reformatting the drive and starting over, when everything else seems to work fine. SolidWorks is the only problem.
