[TxMt] Bibdesk Completion freezes TM. Why? (Working with Latex)

[Flo]

Hi, only since early this morning, whenever I call for Bibdesk- 
Citekey-Completion using "F5" TM freezes, shows the ball and I'm left  
waiting without anything happening.

And I'm pretty sure I didn't change anything since last night, when  
everything just worked fine.
Bibdesk-Completion works in other apps like before.

Any ideas?
