[TxMt] Keybinding Problem

[Mark Eli Kalderon]

I am using TextMate Version 1.5.1 (961). Just noticed that a number  
of built in keybindings no longer work. None of keybindings for  
Text:Convert:to Uppercase, to Lowercase, etc. work (though selecting  
the commands from the menu does). Autocompletion doesn't work either. :(

Any ideas about how to diagnose what is going on?

Thanks in advance. All the best, Mark
