Multiple monitors on laptop: iTunes crashes upon display lock

Question

I have a laptop running XP Pro with an external monitor attached as an extended desktop. When I use iTunes (6.0.5.20) and lock my screen for any reason (close lid, screen saver activates, etc.), iTunes freezes and throws up an "Unsupported Display" window - or at least tries to: it appears in the taskbar but can't be viewed, opened, or closed. Only upon killing it (along with iTunes) can I continue to use my computer.
Anyone have a fix? I'm not the first to run into this; see for example:

Thanks.

Answer 1

I have a desktop with multiple monitors, and I have had the same sorts of problems. For me, iTunes 6 would display a dialog box that says "Unsupported Display" when I unlock the screens, though I was able to see it and dismiss it and life was good. Now, with iTunes 7, I can see that it tried to display an "Unsupported Display" dialog, but it crashed as well...
Here is the stack trace of the crash, in case an Apple Engineer sees this post: (QuickTime.qts 7.1.3.100 and iTunes.exe 7.0.0.70)
