If you now click some place at random do you see "hitting button C"? You might have to create a checkbox or something else that is enabled and handles mouse events.

No but it does eventually catch up when you close the app down. I added a tcl trace to the "do-on-command" procedure and tcl does indeed seem to be calling that procedure at the correct time.

I have a theory that altering defcommand to make it use a command created by TclCreateObjCommand (as opposed to TclCreateCommand) might make it work. I'll send a patch if it does.
