Version: 1.10.1 (using 4.1.2 (KDE 4.1.2), Kubuntu packages) Compiler: cc OS: Linux (i686) release 2.6.27-4-generic When you click in a message (with previewer on), "Select All Messages" from the Edit menu works, but the shortcut key does not.
I confirm this for KDE 4.3.85. It used to work up until on KDE 4.3.4 but stopped working in KDE 4.4 Beta 2. Reproduceable: Go into a mail folder, klick the first mail in list (with preview pane enabled) and press hotkey [CTRL]+[A]: The text in the preview pane is selected instead of the messages in the list (like it used to work before).
