I want a button to disappear when a field is empty and appear the
instant a user types a character into it.  My code looks like this:

on keyDown theParm
  send "keyDown" && theParm to this card
  if me is empty then
    hide card button "button"
  else
    show card button "button"
  end if
end keyDown

It works fine, except when the user types a space.  Then the message
gets confused.  What gets passed is probably "keyDown  " and the second
space isn't interpreted as the key.  Is there a good way around this?
I'd like to avoid any hacks.
