When I got my new Dell Inspirion 1501 laptop, one of the first things I did was port my email from Outlook Express that was on my old Windows XP desktop.
Ever since, every time I open Vista Mail, the CPU shoots up to 100%, and stays there for hours. I finally, accidentally, figured out the cause. I was looking for certain files on my hard drive, and noticed I had hundreds and hundreds of zero-byte EML files. So I searched for all EML files (using Agent Ransack), and found 41,000 of them - 30,000 of which were zero-byte!
After I deleted the empty ones, Mail immediately started behaving normally. Of course, that was three days ago, and when I checked just now, I see I have 284 empty EML files. Haven't Googled to see what may be going on, but I'm just glad for now Mail works correctly. For a while, at least. Now if I could just get any screen saver to start working again...
