Removal of morphicStartUpWithCaption:icon:at:allowKeyboard: from PopUpMenu
breaks StandardFileMenu (try:  StandardFileMenu oldFile). Perhaps you
removed it because it has no senders. That's because the selector is created
from the concatenation of 'morphic' and
startUpWithCaption:icon:at:allowKeyboard in Project (see below). It was
recently added by David T. Lewis to manage Morphic and MVC compatibility.

dispatchTo: requestor addPrefixAndSend: baseSelector withArguments:
	"Sender wants to perform a method with dependencies on the type of project.
	Dispatch to an appropriate method for the current project.
	This method is a workaround for lack of proper ToolBuilder support in the
	and should be eliminated when possible (dtl Feb 2010)"

	| selector |
	"Flag target selectors to help identify senders"
