[AccessD] Form BeforeUpdate

Hey All
I am trying to use the BeforeUpdate on a bound continuous form. The code 
works and checks the data in the current record for validation and if an 
error is found it pops up a message and fires the docmd.cancelevent (or 
cancel = true).
Everything works fine, except when I click on the add, delete, or close 
buttons (mine) in the form's footer, then the code works fine and the 
message pops up, but the docmd.cancelevent doesn't fire. Is this a bug, 
or am I missing something.
