Mouse Failure

I like sniping on War Rock but like, when i press my right-mouse button to zoom in.. It zooms in twice when i press it once.. and theres nothing wrong with my mouse.

any ideas?

Restart you computer, try that.
that's happen to me before i just took my mouse out and blew into the port and re plugged it.

I dont restarting my computer will help but i could unplug my mouse and plug back in.

It's a very delicate mouse too.
