Hi Gunter, what does your keyboard shortcut look like?

Do you possibly have it as the following:

script: UnwrapCurve

If so, then that's the problem - you need to put just plain "UnwrapCurve" in there, when a keyboard shortcut starts with script: it should then contain all the actual script code embedded directly right after it. If you are putting in the name of a command to load, it should not have that "script:" label in front of it. So make your keyboard shortcut to be just :

UnwrapCurve

and that will solve it, if that was the problem.
