Hello
I was trying to disable this from my tool bar and inadvertently hit disable.
Obviously, when I boot into guest on my laptop I cannot use the mouse.
How can I get it working again?
Thank you

??? What toolbar? I don't see any way to enable/disable a pointing device from and toolbar I have?

Perhaps a System Restore to before you did this would fix the problem since it's most likely a registry setting.

My issue is resolved.
For some reason, I saw an icon in my tool bar in the lower rt. corner so I hovered my cursor and it said 'pointing decvice'.
I clicked on it and, in error, disabled it instead of removing the icon.
I have since been informed that this is a default guest account and cannot be removed or fixed as the mouse is disabled so I accepted the mistake and created a new limitted account.
I was determined to repair was cannot be repaired.

Unfortunately, you are not alone in this pastime. There is a whole host of us right there with you!

What i did brings to mind,"Think twice before you click once!"
Although there is no harm done, it still irks me that I was in such a hurry. It is a good reminder, though.
Happy T-Day to all.
