Hi Ed, I can confirm it is definitely related to ⌘-Z (undo) via keyboard. Mostly multiple undo's. I aso do not have a pattern. It happens... and when it happens only a full quit of TM only works. One thing for sure, the project folder make use of GIT bundle. == Feek -- Sent from: http://textmate.1073791.n5.nabble.com/textmate-users-f3.html
