One solution to both problems is to time the hiding/showing of the button until
the enter key is pressed, ie when you have finished entering text in the field.
The script in the field could be something like:

on EnterInField
   if [card] field <fieldname> is empty then
      hide [background] button <buttonname>
   else
      show [background] button <buttonname>
   end if
   pass EnterInField
end EnterInField

This is a fairly simple answer, and may not be quite what you need; however,
since you presumably wouldn't want to press the button until you've finished
entering text, it shouldn't be a problem from that aspect.

Hope it helps!
