Found this strange one. Could be a kontact problem, could be a KDE problem....


If I start kontact by clicking on the kontact icon
move to a differnent virtual desktop
click the kontact icon again, the current kontact session is brought to my
virtual desktop. 

If I then
then end the session
then log back in again so kontact is restarted at part of the session restore. 
then click on the kontact icon, I get the error "Kontact already seems to be
runningo n another display on this machine. Rnning kontact more than once can
cause the loss of mail. You should not start kontact unless you are sure that is
is not aready running"
What's worse, is that this error is on the same virtual desktop the current
version of kontact is on, not the one that has focus.
