|Seems like "things" the dude is talking about is a browser window? I have a wireless mouse that does about the same thing and a couple of wired that don't.|
Like Jennifer said, I'd try a different mouse. You currently have no idea if it's the problem or not.
"It is not the mouse because the computer is responding."
Who cares? A computer will respond with no mouse whatsoever attached. Maybe your left click button sucks...you need to find out and another known good mouse is the way to find out.
