We need the ability to cancel any in-progress operation. I'm currently sitting here waiting for Vectorworks to convert an object to an auto-hybrid, and it's taking forever. I didn't think it was a very complicated object, and I don't even need it to be auto-hybrid, but I can't cancel the operation. I hit escape and nothing happens. I'm pretty sure my only option is to wait (is it even doing anything? how long will this take?) or to force quit, which I really don't want to do since I haven't save
