OK, well, I just found out that the guy who originally had this problem (I
posted this here in order to try and help the guy), is using this form as a
modal dialog (which, if I had thought about it a little more, I would have
realized from the get-go), so I told him that he doesn't need to close it.
Just perform the click of his accept button.

Still, I wonder if there is any other way around this (in case there is a
legitimate need for this kind of functionality)?
