"File Open" Window Doesn't Display Correctly

I have a problem running Patran 2007 in Windows 7, the program seems to run fine, and I am able to open data bases and work on them. The problem comes in when I want to either save the database, open a new database or just open a current database. For each of these functions a new smaller window pops up so I can navigate to the correct file or path to click on it or whatever.

Initially the window opens as I would expect, but as soon as I move the mouse or try to use the keyboard to navigate, the window goes blank and I can do nothing with it. Strangely, using the compatibility setting to open the program in a 640x480 display, they do seem to work fine, but because of the small resolution, I cannot actually see the part of the window where the files are - so that also doesn't help me.

It seems as though there is something between Patran and Windows that one of them don't like, but it baffles me that everything else works fine. If any one else has had the same problem, maybe with a different program even, let me know what you did to resolve it. Otherwise any advise would be useful.
