At random times, ususally when I'm organizing my files, Windows Explorer will randomly crash, and when I restart it, it'll be fine.  This can happen multiple times a day or not at all.  I can't check the error logs right now since I dual boot with Ubuntu(even KDE4(still in heavy development) is more stable than Vista), but if anyone else has come upon a similar problem, it would be helpful.

I'm on an Inspiron 1520, have all the updates installed (including SP1, hoped it would fix it), and have an Nvidia card.  It started happening about a month or so after I got my laptop, I've reinstalled Windows completely since then.

If you need extra info, just ask.
