The menu builder tool assigns a blank script to the menu buttons if you click its auto-script button. That provides a structure you can fill in with various commands, but if you don't do that, the menuPick handler effectively blocks the actions in its case statements. The fix is to not click "autoscript", or delete the unfinished menupick handler, or remove the menubar assignment. Or better, just add some code to the menu items in the menuPick handler.
I've often thought that the auto-script feature should be slightly expanded. I understand why it shouldn't put in default statements for many of the items, but it would cause less trouble if it could add the one-word commands needed to activate the items in the Edit menu.
