Creo 2, M120, Nvidia Quadro K3100M, driver version 340.66
I've noticed that occasionally highlighting stops working and I cannot choose "smart' in the filter at the lower right. When this happens, it effects only one window, the others work normally. Sometimes I can get full functionality back by activating another window and coming back, closing the window and re-opening the part or similar actions. Other times, I have to re-start Creo.
It effectively makes Creo useless as you can't select anything reliably.
Anyone run into this and have a fix?
