Thanks to everyone for the responses. After checking numerous things
and watching the cpu usage in the task manager I discovered it has
something to do with the driver for my SpaceNavigator (spaceball). If I
disable the spaceball then Pro/E works fine but with it on everything
comes to a halt. Again I made no changes or updates to the spaceball
and maybe it is only a symptom and not the real cause. I will remove
and re-install the driver to see if that fixes it.
I am going again for now. Thanks again for all the help!!
