Welcome to the forums,
I don't know why you don't have the top frame to the program. Have you tried resizing your display? The program could also be displaying Maximum, instead of Window sized. Have you tried resizing the window?
I have PSPx2 installed on a laptop that is running Vista HP. I noticed that I have set the DEP (Date Execution Prevention) for PSP, so it must have posed a problem warranting setting that. DEP generally will think that a program may due harm to your system and will prevent the program from running. I don't know if it will correct your problem bu you can try it.
To set DEP in Vista go to Control Panel, then select Performance and Information Tools. From there select Adjust Visual Effects. In the Performance Options window go to the last tab, Data Execution and Prevention.
Now on the DEP tab, go to the bottom and select Add. A browse window will open, browse to the executable file for PI-X3, which should be found in the C:\Program Files\Corel\Corel Paint Shop Pro Photo X2 directory. The specific file would be Corel PaintShop Pro Photo.exe. Select it to add it to the DEP.
If the above does not work you can always remove it from DEP..
You can also try setting the Visual settings to Best Performance. This will free up some resources that Vista hogs with all it's cosmetic crap..
