I finally found a way to MAKE my game crash! :)  Start up the game, go into settings, weapons, weapon priority, game frezzes and locks up.  It doesn't crash, I get no errors, the computer and windows are still perfectly usable and I can end the UT3.exe in the task manager.

I'm running the UT3 map mixer thing for the frontend layout - I don't think this is part of the problem.
I reinstalled the last patch I have, UT3Patch3.exe and it chn=anged nothing.
I started experimenting with my config folder - delted the current and restored one of my old backups of it.  Still had the problem.

Then I deleted the config folder and started the game.  It asked for the CD key and for my name and pass... so I quit the game and restored the UTGame, UTEngine and UTInput ini files.  Then the mapmixer frontend wasn't right, so I put the ini files for that back in so it would be as it should be.  I got into the weapon priority screen this way.  This is what I see:

Any thoughts?  Is there a particular file that might be corrupted?
