Just FYI -
Running W10 Anniversary Pro 64
Start Pf3 ( as admin or not - same issue) - after it opens - select Options #1 - do something or do nothing - makes no difference - close Options - immediately get a Pf3 has stopped working, etc - close program. Doing ANYTHING other than option #1 - all ok.
Happens every time.
Fix - run PF3 in W7 compatibility mode - no problem at all.
