Version: (using KDE KDE 3.4.0)
Installed from: Compiled From Sources
Sometimes, after login, Kontact displays the following warning message:
"Kontact already seems to be running on another display (...)"
There are two buttons "Start Kontact" and "Exit", but none of these buttons work!
To start Kontact I need to close warning message by clicking on the "X" button,
then start KMail and click "Start KMail"...
Maybe Kontact and/or KMail has problem with session save/restore?
I think I've also met this "not-working behaviour" for the Start/Exit buttons.
Funny thing is that, now that I have enforced some properties for the Kontact window (such as Vert/Horiz Maximized: yes, NoBorder:yes, Desktop:PIM) I can no longer get that error, even on subsequents starts. It doesn't even switch to the corresponding desktop.
