Mouse double-clicks on screen even though I'm only single-clicking

Hi all,

I've been suffering with this problem for months now. I've long thought it was just a software bug that would get fixed with an update. But it hasn't.

Now I'm not sure if it's a software bug or I just need to get a new mouse.

I've checked my settings to make sure everything is normal.

I'm not sure what's causing it, but it's a real pain to have it double click when you only want it to single click. Just imagine all of the troubles an unwanted double-click brings!

Any help is much appreciated.

Thanks.
