starting the curve tool brings me into a big problem and this dialog pops up:

Traceback (most recent call last):

Am I the only one with this problem?
Thanks for help

I tried it on H 20.0.527 and I can't confirm. Try it with a fresh user preference folder and see if the problem persists.

OK it works on new files, but I have a lot to do on older files... so I copy and paste an old "curve" and work on... that works for me but I don't like it.
Thanks
