ALT-TAB and Quicken

When I use ALT-TAB (on Windows XP) to switch between Quicken and some other program (usually a browser open on a bank site), I find that switching away from Quicken works normally, but switching back to Quicken produces some oddball display. While holding down ALT and having pressed TAB once, when it should show a little window with the icons of all the other running programs, it also shows what seems to be all the Quicken header bars on top of the previous program's window. This is hard to explain, but if you have seen it you will know what I'm talking about. Is this standard Quicken behavior or do I have something configured wrong?
