Mouse doesn't open anything in the toolbar any more!

[Ashley Benton]

Hi,
I was putting some applets on my toolbar when an error report showed
up and froze the system. As I didn't know what to do or which
application to kill I rebooted the computer. Now I have trouble with
my mouse. I can see the arrow of the mouse and move it, if I right
click on the screen or click on something that is on the desktop that
works but if I try the toolbar nothing happen. Does anybody have any
idea of what I should do? Right now I am stuck out of my home and
everything that is on the toolbar.
I am using ubuntu 6.10
Thank you
Meg
