Something peculiar is going on when copying different versions of a script to the MoI command directory, and using customUI.

A functional script named _TrimCurve07.js, and .htm is in MoI's command directory.

A copy of the script named "_TrimCurve07 - Copy" is modified a little bit, with a missing "curve" variable, and copied to the MoI command directory.
The - Copy (seems) to run in MoI

If the defective "_TrimCurve07 - Copy" is renamed to "_TrimCurve08" it does not work.

So the lesson is do not use " - Copy" versions when testing.

This happened a couple of months ago... when this "crazy" behavior was first encountered.
This example is on a different computer...
