Version: (using KDE 3.5.10) OS: Linux Installed from: Fedora RPMs KMail used to work fine. I had to reboot due to a system lockup and found that I had lost my ethernet connection.

I don't know if it's related, but now KMail starts up with a single blank page rather than the documented "The main window is the window that appears when KMail is started. It is by default divided into three panes:"
