GtkRadiant preference files?

[Supertanker]

Is it possible to chang where GTKRadiant (1.5) saves it's preference files? Like preferably, the directory it's actually INSTALLED in? I'm trying to get it to run off of a flash drive without writing to the hard drive.

A .bat or shell script?  Only other thing I can think of would be a custom compile...

You might have to modify the source. Just find the text ".radiant" and you might find the hardcoded location for it.
