Mouse problem

My mouse has a problem where I click once and it acts like 2 clicks. an example is where I click a URL in my browser which is google chrome, it automatically selects all the text, another example is in YouTube when I watch a video and click to pause the video the video goes full screen. My other problem is dragging tabs or windows when I left-click and hold a window it holds on and lets go consecutively. This became really annoying, help

It's most likely a faulty mouse. Can you try another mouse just to be sure.

There was a thread a few weeks ago with a similar problem to yours & the owner of the mouse was able to dismantle & clean it, with some success.

Mouse double clicks with only one click

my mouse is a logitech g100 gaming mouse, should be good.

Look in folder options and see if you have single click selected.

the one that I have selected is the double-click one.
