It appears to be a mouse driver issue. If you use the standard windows driver update, it will show it is up to date....but it is not! I had to go directly to the mouse driver company and download the current driver and then install it overtop of the existing driver. It was a pain, but helped the problem a bunch. It still exists, but not to the same level. I was clicking 10-15 times every time to get it to take, now occasionally it is 2-3 times. So, its at least bearable now. I have heard that I need to run java runtime 51 (I'm currently using java 8 update 91), but I haven't slowed down to figure that out yet.
Related or not I don't know, but creo 2 and 3 were crashing, while saving or changing windows, with an error of..."fatal error encountered. a traceback has been written to blah blah." That seems to have gone away as well.
