When I attempt to open the Preferences window in Mail, nothing happens. No dialog box, no error, nothing. Mail itself doesn't crash. I moved com.apple.mail.plist out of the way to see if it would fix the problem, but that didn't work (I set up the mail account again and went to Preferences and nothing happened). I'm running 10.5.4 on a MBP; I beleve the problem has been around since 10.4.?. Are there any other plist files I need to blow away? Reistall Mail? Are there any logs I can look at? Thanks...
