Left click sometimes does strange things

[pdxuser]

My laptop keyboard and mouse keys are starting to wear out, but one problem seems particularly curious. The left click on my touchpad mostly works normally, except in a few situations. In Chrome (but not IE), when I click on a tab, the tab closes. I'm not clicking the X or anywhere near it. Also, when I click on Chrome's back button, the previous page opens in a new tab, rather than it sending me back within the same tab. And it's not just Chrome. Sometimes when I click on a program window, Windows "unfocuses" that window, so the window title bar turns a lighter shade, like I've clicked on something outside the window.

I'm wondering if Windows thinks I'm holding down a key when I'm clicking my mouse? I've tried to find info about Chrome that would suggest what would make a left click behave this way, but I'm stumped.

Does everything run fine with the touchpad?
If so its your mouse.
You either need new batteries or a new mouse.
Or you'd need a wired mouse.

Also try a different browser like Mozilla Firefox.
Is their a difference?
Run a system scan with AVG anti virus.

Download and Run CCleaner.

Hope this helps

Sorry, I'm not using a mouse. "Clicking my touchpad" just sounded weird to me. It's when I click the left button on my touchpad.

I've actually just replaced the hard drive, and I have the same problem as with the previous hard drive, and a system scan found no threats. So it's not the software.

I get the "unfocus when clicked" problem in lots of different applications, so it's a system-wide thing. But there are peculiarities in different programs.

Also, this problem comes and goes.
