Does anyone know of a way to clear the favorites list when inserting an item from the toolbox?

I've been playing around with the toolbox the past few days, specifically bolts/screw and ended up having a favorite being created for each possible configuration for ANSI SHCS, over 2000. As best I can remember, I didn't automatically create configurations as is possible in the nearly hidden pull-down in the possible configurations table, but maybe I did by mistake.

I've tried copying a "clean" file from a un-touched toolbox installation, but the favorites are still there. I can't seem to find out where in the system the "favorites" list is stored, and I don't want to go through and manually delete >2000 from the list.

This toolbox would be a great tool, if it were easier to use/configure.

Thanks,

Jon
