Version: 1.9.1 (using KDE 3.5.0, Mandriva Linux Cooker x86_64 - Cooker) Compiler: Target: x86_64-mandriva-linux-gnu OS: Linux (x86_64) release 2.6.12-12mdk I removed a Imap account while kmail was getting emails. This freezes the downloading process (not the program). I tried to press the cancel button to stop it but it didn't close.
KDE 3.5 is unmaintained. The behaviours has not improved since. Look at bug #206877
