klipper autostart ignored

[Dj YB]

Hello,
I have added the klipper desktop file to the kde autostart directory along with 
other desktop files like cairo-dock,all other applications run at startup but 
for some reason klipper doesn't, the desktop file is fine, I use it to start 
klipper after the startup.
any advice how to solve this problem would be great.

Thanks,
YB.
