Same issue as sjukmidlands.
Not prompted to enter key.
Clicked on animation object at it's top left corner (after using the obvious button at lower corner to set location and measurement settings) and was prompted to enter preferrence for animation speed fast, medium, slow.
I entered medium, and the object proceeded to drop the black textured border. Clicking in the top left corner failed to produce the preferrence prompt again.
A bit confusing after that.
I like the idea, and look forward to updates. Would like to request some basic documentation to give us an idea of what customization capabilities are available.
BTW, Norton Antivirus still does not like this type of script.
Nevertheless, great effort. Can't wait for a bit more configuration friendly version.
