Start up window not working

When I left click the start up icon I get a message: Critical Error, Start Up Window isn't functioning. Will try to fix when you re-start. The Error message prevents all other windows from opening. When I click the message, the system re-boots, but the Error continues.
If I do not left click the icon, everything works properly, and when I right click the icon, everything works too, including the shut down process, the searches, etc.
Hummm? Suggestions?

Hi,

I'm not too sure what you mean. Are you talking about the 'start button' in the bottom-left corner??

yes -- start button doesn't work with left click
