Yes, I think that should work. For the onClick, you'd need a
Javascript function that checks if the popup is needed and then sets
the form.target value before invoking form.submit(). If you decide not
to submit, then just return false from the function. I don't recall if
target is a readonly property or not, so you should double-check that.
