Welcome to the forum.
Do you mean the entire GUI of PrPro, or just one of the Panels?
I would look into Resetting the WorkSpace first, to see if that clears up the issue.
If not, I would trash the Prefs for PrPro, to see if it's from a corrupt Prefs file.
If you still have no luck, then perhaps post much more detail, so that we know what you are faced with, and probably a screen-cap of what you are seeing.
I don't understand the question. Proper punctuation, capitalization and grammar go a long way towards making your communication comprehendible.
