I have a form with several combo boxes on it, the last of which allows the
user to type in new data.  Depending on the contents of all of the combo
boxes, a routine executed in the before_update event enables or disables a
command button.  The users don't learn to tab off of the combo box after
typing new data into it because when they choose from the list, the command
button gets enabled or disabled immediately.   I can't find any way to
ascertain the contents of that last combobox until the user tabs off of it.
Key_up and similar events only know about the previous contents.  Can anyone
think of a way for my enable/disable routine to "know" about the new
(visible) contents of the combobox before the user tabs off?
