Just thought I'd report an odd behavior. I auto-installed the newest version 611. Closed Textmate. Reopened it.
Clicked on a file in the drawer to open it. The odd thing is the the font size was wrong. It looked to be 1 size smaller than I had set it before. So I go to Preferences and try to reset the font size. It didn't take. Close Preferences and reopen to try again. Still stuck in something like size 8. I'm using ProFont.
Finally closed the TextMate again with the font set at something huge like 132. Reopened TextMate. Now the font sizing kicked in and resizing works again. I cannot reproduce so don't know if you should be wasting time looking at what's causing this.
Thanks, Ed Wong
