Hi fiveelement, how exactly have you set up the shortcut to run the command?

Another possible installation problem is if you made the shortcut say: RebuildCurve.js instead of just plain RebuildCurve (note, no .js at the end).

To have this one run correctly (as a "command" that has a companion UI file rather than as an "inline script") your shortcut should be set as just plain RebuildCurve with no .js at the end.

Is that possibly what you have run into?

If that wasn't it, can you please let me know which version of MoI you are trying to use it with?
