Software issue/involuntary mouse click  

First off, let me state this is not a problem with Windows 7, I had with Vista briefly before I upgraded.

Mouse (touchpad or external) involuntarily left clicks itself. I have tried different mice, no difference. It happens more commonly when typing in text boxes in the web or using Office/text applications.

I've run extensive anti-malware/spyware and virus scanners.

Anyone have any suggestions? Much appreciated.

I tried updating the driver, and also rolling back. No difference.

Thanks for the welcome :)

I always run it with the power cable, without battery. I guess now I'll try it with the battery, see if that makes a difference.

Changing mouse movement speed made no difference.

I know what you're going for... I had heard of laptops where bad power connections caused slight fluctuations in electrical power causing involuntary mouse clicks.

I've just tried running the laptop off a fully charged battery - no difference. I'll try cleaning the AC connection and battery compartment next. I'm also gonna try plugging it directly into the wall instead of a multi-plug...

Argh...this is the most infuriating problem.

Most common reason to this is a sensitive touchpad. Even if user does not notice it, part of the hand touches touchpad when typing, causing involuntary mouse movements or clicks.

A simple method to test if this is a reason is to connect an external keyboard to the laptop, so that hands don't go near touchpad when typing. If this "solves" the issue, I recommend disabling touchpad and only using external mouse or trackball.

LOL, this was it. I discounted this possibility because my touchpad doesn't actually click with one touch, there is a separate mechanical button. However, I've found out that with a driver update, it now does click by touch.

Thanks for your feedback, everyone.
