[DUG] Customised component and the Enter Key

[Rohit Gupta]

If a receiving form closes on a keydown then the next form can receive 
the keyup (depending on timing and OS and dlls installed).  It happens 
on D5, D6, D7  etc..

This feature has been brought to you by the Illustrious Gates 
consortium.  :-)
