I'm working in DW MX and I set the behavior on a button to Open Browser Window to a set size. The original page containing the button jumps back to the top of the page as soon as the popup is launched... I need to keep the originating page at the spot from which the user clicks the button.

Is this a problem with the behavior? Am I neglecting to set something with the behavior (not much to the behavior dialog box), is it a page properties issue? Any advice?

it's really annoying and I'm at my wits end.
