Rhino5 Hangs on Startup (untill ESC)

I click on the Rhino 5 icon, it opens with the spash screen of recent files etc, but won’t release that window until I hit the escape key (as there is a partial command already waiting for a response) . I am not able to remove the command so that future opening of the program doesn’t have the same problem.

Thank you in advance!

See attached picture:

Hi Gregory - You have a script set to load at startup that is not designed to load at startup, as far as I can see- you’ll need to remove that from your startup scripts (Options > RhinoScript page) and just load it when you need it. Looks like it might be GearGen, maybe?

Thank You Pascal!.. The world would be a more frustrating place without your brilliance.
