I'm sure Allan is all over it, but I noticed an issue with TextMate (v1.5.7) running on Leopard. Clicking the "gear" popup at the bottom of the window and selecting various bundles to see the commands, the text in the menus are different sizes! Some small, some large. I remember seeing this before and it was corrected.

I'll play around more tonight to see if there's some correlation between menu items and text size.
