Version: 1.11.2 (using 4.2.2 (KDE 4.2.2) "release 111", KDE:KDE4:Factory:Desktop / openSUSE_11.1) Compiler: gcc OS: Linux (i686) release 2.6.27.19-3.2-default Drag an email from the pane that shows all the messages to the pane that shows the mailboxes, and a dialog pops up that gives the options "move here", "copy here", and "cancel". If I select "cancel", the dialog pops up again. If I select cancel a second time, the action is finally canceled.
Confirmed in kmail 1.11.90 (kde 4.2.70).
This doesn't happen any more in trunk r978730, so should be fixed in 4.3 beta.
Right, I think it was fixed at some point, closing as resolved.
