Right now, when you have Shape: Clipboard enabled, but nothing on the Clipboard, then you literally draw a blank. It can be very confusing upon start-up, especially since the warning message isn't in a very visible position. Users are bound to get confused if they're unfamiliar with the Shape feature, I thought there was something wrong with my development build at fist. Here's a rather simple solution: when there's nothing on the Clipboard, then have a default where the resulting path is a normal path with no shape applied. Problem solved. The warning message (Nothing on the Clipboard) can still be displayed.
