Hey Brian,
THe dialog sizes are not saved as part of the file. They are unique to the Work Environment on each machine. You can transfer Work Environments, too, via export/import ... but it sounds like the issue is that your PowerBook WE just happens to have a bad setting that coincidentally mimics your other computer.
At worst, you could import just the Palette Scheme from a standard profile into your laptop WE... At best, maybe you can temporarily plug in an external monitor if the powerbook card can drive it at a higher resolution to allow you to find and shrink the dialog?
