I don't think I expressed myself well.

For example, I have button (being a hyperlink button or push button) in a
datagrid. When the user selects it, is causes a postback. In the post back
code, I am building js window.open function that I append to the output of
the page with Page.RegisterStartupScript. (I am dynamically building the
querystring). How does/should a pop-up blocker treat this situation? My
pop-up blockers are allowing it, some or not.
