The key sequence crtl-esc not activating the bundle menu anymore.
I have already logged in as a different 'virign' user and temporarily moved my /Librabry/Application Support/Textmate/ folder to another location, but still the problem exists.
Has anyone else encountered this problem,
Yes.
and if so were you able to solve it?
No. :(
I tried every fixes I read about: Setting the prefs in Terminal (I don't remember the exact command), setting it in KeyBindings.dict, creating a new account... No go.
