>However, I'm stuck for ideas on how to disable the toolbar buttons. I can't disable the TL menu, obviously (which could be one way to do it), but then the modal edits won't work either. In the toolbar edit buttons is an added property:

Major Duh...on the commute home, realized was making a mountain out of a you-know-what...

All I needed was a TL property, call it lModal for the modal entry and exit TL methods:

Enter a modal: topmain.lModal = .T.
Exit modal: topmain.lModal = .F.

Code added to top of toolbar Timer event (to poll for edits):

if topmain.lModal
  return
endif

Works fine, super-simple, and no need to mess with vfp internal edit functionality. Thinking too hard or something, I guess, just needed to step back and take a fresh look...
