Hi Dave,
I fired up my system and gave it a test, I set the skin to default and then when to options#1 I changed any of the setting and then clicked close. I this got the popup window that PF3 had stopped working, I closed the first window and then it popped up again. clicked close again and then PF3 shutdown.
I have attached vi drop box my log files and pictures of the windows I see and also a picture of my windows event viewer, all the red errors you see refer to the same faulting module path.
I hoe this helps and shout if you need any further information
