>Sometimes when (large) forms get pushed up too high on the screen, the close box goes under the menu and can't be accessed. If there is no other exit/close button on the form, I can't close it - the only answer is to crash the db. Is it possible to stop this form behaviour? Many thanks in advance.

Denis,
If you mean w/o a single line of code use Ctrl+F7 to move and/or Ctrl+F8 to size form with keyboard.
