I would restart holing down the command and R keys and reinstall the Lion OSX. Your settings will be preserved. Seems very strange but I believe a reinstall may fix your issues.

No, Pete, it's no help for me. I have reinstalled one time, but this issue comes back again. Now i only use logout to fix this issue, but after sometime, it will be back.
Maybe i only hope 10.7.4 can fix it.
Still thank you!

I have the exact same problem.
I haven't found a soulution yet, although rebooting sometimes fixes it until I reboot the next time, then it seems to be a matter of luck whether or not the problem re-occurs.
I recently installed a SSD and used CCC to copy my data across and wondered if this could be the cause, although things seemed to be fine after this, the whole thing went very smoothly.
The problem actually started for me a few days later when I downloaded an update to Adobe Reader to version 10.1.3. Does anyone know if I can undo this
I was going to try a clean install of Lion, but having read that you tried this and it didn't solve the problem anm beggining to wonder what to do?
If anyone can shed any light on this would be grateful.
MacBook Pro OS X Lion 10.7.3
Found a solution that worked at CNET.
Seems like a common problem, just took a while to find an answer.
Open Terminal, type, or safer, copy and paste:
killall DockHit returnMission control back to normal :-)
