You really need to look at what you are doing while using the mouse.

Some of the most common causes of this problem is large breasted women leaning on the touch pad or keyboard, the users non-mouse hand leaning on touch pad, keyboard or graphics tablet or the family cat is asleep on something important.

So do you lean on anything with your non mouse hand while using the mouse????:^O

(I dare not ask if you have a large rack:^O)

Tthanks so much for your helpful reply I really appreciate it and am forever grateful.  .

No, I don't have a large rack. 

Yes I have been resting my non-mouse hand on the touchpad.

So now you've totally embarrassed me in front of the community

go away and laugh yourself silly. 

:^O :^O   :^O    :^O

Evil Bump strikes again ! :^O

Sounds like a browser configuration problem, or some other configuartion problem.

Try using a different web browser. Also, is your mouse wirelss?

Thanks Moonlight,   I had gone right back into devices

and tweaked here and there, but the polite lady above was

correct -    I had been resting my left hand onto the touch

pad.  My bad.       😞

:^O:^O:^O:^O:-p

OK Deja, at least I'm honest.   X-(        :^O

WARNING: Dangerous mouse ! 😉
