I am having problems with Femap 11.1.2 freezing on me randomly when a file dialog opens. It doesn't happen all the time, but the times I've noticed this version freezing have all been when some sort of file dialog is open. My OS is Windows 7 64 bit.
We had a single large customer that had this problem over a year ago, and for some reason it just went away. We could never figure out exactly what was going on, and it only affected a few machines out of hundreds, I still believe it was somehow network related. The next time it happens, if you could go into Event Viewer, and in the "Windows Logs" portion, see if there is any error information being gathered and we can try to figure this out.
E-mail me directly if you would like to work through this -
