I upgraded to the latest sublime text (Sublime Text 2 Beta, Build 2165) the day it came out and the auto complete doesn't close when I hit escape. My co-workers aren't experiencing this. Any ideas?
Check your User keybindings? Do any messages appear in the console (Ctrl + `)?
User Keybindings had something for escape that didn't appear to be doing anything. Must have copied a couple of bindings in that nerfed it. Thanks!
