I discovered this quite by accident, and am not sure if it qualifies as a bug.
I was logged in to my laptop as one user, and had a project open in TextMate 2.0alpha. Then I logged in as another user and tried to open a project, and though TM launched, the project wouldn't open. Though I could create new files, any directory I tried to open would fail.
Only when I switched back to the original user and closed the open project did opening a project work in the second instance of TextMate.
Is this a bug? A by-design behavior? Please let me know.
Thanks, Richa
