I'm not sure who to assign this bug to or if I have selected the right component. Please adjust as necessary. I started Messenger with a clean mozilla registry file (hadn't set up mail prefs). When I did that I was prompted with the "New Messenger Account Wizard." I filled in the first screen and then was prompted for my "incoming server." Because I can't change it to the appropriate type (IMAP), I didn't fill in the server name. I entered "nsmail-2.mcom.com." as my outgoing smtp server since I needed to be able to send mail. When I then clicked Next I crashed. Part of the stack crawl is the destructors for nsMacWindow, nsChildWindow, and nsWindow. This may be a duplicate of the widget bug on mac (does it exist?) since on a second try of the wizard, I didn't touch the drop down list (combobox?) for server type and I was able to proceed without a crash.

The part of being unable to change to IMAP and crashing attempting to do and then clicking Finish is bug 14398 which was marked a dup of bug 14146
