Problem with kde after update

Hello!
I have problem after i had update my kde4. Kde4 start to work slower. It so slow that i could not working. I discovered that after update tray(i don’t have english version of opensuse so i don’t know how it real named in kde so i call it tray because it similar to tray in windows) do have all icons one on the other and that the tray slowing my computer. Second problem is that i saw that some config of kde is not saving. For example after reboot something go wrong with my cube desktop. What should i do?
Thanks for any help:D

It might be worth changing the system file .kde4 (in your home directory) to .kde4old. Then if you log back on the file will be recreated and with luck fix your problems.
