I have the same problem with my kids' laptop, an hp pavilion zv5340us. I am not an IT professional, but I do know my way around windows.
I don't know what they were doing when the problem occurred. Even when I use IE 6's File, New, Window, it opens the new one, then closes the original. The original also closes when clicking a web-link opens a new window.
Checking the Tools, Internet Options..., Advanced tab, I made sure "Reuse windows for launching shortcuts" was cleared (it already was).
Spybot Search & Destroy 1.4 and AdAwareSE 1.06r1 both come up with nothing but the usual tracking cookies. Oh, it also has OpenOffice 1.3 installed, GAIM, Yahoo Messenger, and does get used for games like SIMS 2 and Age of Mythology. They surf with NetZero, had a problem with not clearing the connection dialog, i just installed a NetZero update, still only One IE Window! I recently activated wireless networking, but it did not help either (didn't expect it to).
Is this a new problem? (I have yet to run windows update on them)
oops! Finally saw the replies, I did notice they have Yahoo Companion installed, I will check it out (personally, I avoid running all those "conveniences", maybe that's why my machines have been running for 5 years, surviving hardware and software upgrades without having to reformat and reload).
