Dave,
As I've already indicated in an image of PF3 to you via email as well as my description here in this forum, the issue was never inside FSX. The issue is PF3 normal window when it's first opened as an application. If Windows Display settings ( Personalize\Display\ text size) is set at a size larger than 100%( Windows has 3 modes- small , medium, large text), some parts of PF3 text becomes corrupt. It will only display correctly if Windows Display is set at 100% or small mode.
Also, I noticed that when PF3 "Option 1" window is closed, PF3 shuts down.

Sorry, my bad, I've been jumping from one post to another then emails then... etc, etc, got a little messed up like your display
If the program suddenly closes on you that's indicative of a skinning problem that some get and some don't. Try another skin or disable them altogether if necessary.
