Hi,
I have put a link to Skype in my Autostart folder to have Skype start at boot time. But if it's open at shut down, KDE remembers this and will start it again at the next login. So, then Skype runs twice and I'll have to close one instance. I don't have this problem with other programs, that I start in the Autostart folder.
Please prevent multiple instances of Skype.
Rgds,
Edwin
