strange problem with keyboard/mouse

[linuxlizard]

Hello,

I've got 3 users with seperate accounts on my hardy heron system (myself and my 2 sons). One user account has had a couple of weird problems since it was set up. The symptoms are:

The middle mouse button is not opening new tabs in firefox.

The letter c isn't working on the keyboard.

These problems do not exist in the other 2 user accounts.

Anyone know what the problem is and what the fix is?

Thanks much

You could try creating a new account to replace the broken account.
