[comp.sys.mac.hypercard] HyperCard Screen Updating Quirks

  In case anybody cares, here's the screen-update workaround I'm using
for when a field is modified and I intercept 'keyDown' to set a flag to
(later) reformat the field:
  What was   pass keyDown
  is now     send "keyDown ch" to this bg
             get selectedChunk()
             lock screen
             unlock screen
             select it
