I just filed-in the code into a clean 2.8a #1919 image.  It took a while to
load while the Controller class hierarchy was recompiled.  It also asked
whether I really want to move YellowButtonMessages to undeclared and I agreed.

But for me it works.

If you call the method I mentioned (I unfortunately forgot to mention that
it was a class method) and then try to open the text pane's menu, you'll
get an error.

I fixed that but that broke the BitEditor and the FormEditor class.

This was because all three classes use the same method
MouseMenuController>>yellowButtonActivity, but with PopupMenu and
SelectionMenu instances and these classes aren't compatible.

It's not a problem of the PopupMenu hierarchy but of senders of these menu
instances.  The original code assumes PopupMenus but with the exception of
BitEditor and FormEditor all other controllers assume SelectionMenu
instances.  Most controllers use their own yellowButtonActivity.  Not so
the FillInTheBlankController.

Andrew, if my code breaks your system, could you please give me a hint what
fails so that we can work on a solution?  Did you tried to file in the code
into a fresh image?
