Left click on touchpad is "sticky"/gets stuck.

I have a brand new Dell XPS 15 with the Haswell processor (I've only had it for about a month).

I have noticed that the left click of the trackpad sometimes gets "stuck" when I click it and the pointer stays "active" until remedied by right clicking. Examples of what I mean:

• Scrolling will get "stuck" after I left click to drag the scroll bar up and down. It is not relieved by left clicking again. It is relieved by right clicking.
• When selecting icons, the selection box will not release and continue to drag the selection box across the screen until relieved by right clicking.
• Selecting text, the selection will not "release" and will continue to select text

Hopefully this is enough to explain my situation and problem. I am hoping there is a solution to this. In fact, most of this message is copy-pasted from this thread, because it's the same exact problem you've been having with this model for more than a year:

Updating the drivers etc. doesn't help. Also, when it happens, the sound is different -- there's either a click and the touchpad works or there isn't a click and the touchpad is stuck.

Also, I can't return it -- I use it all day every day for my job. I'll need it fixed at my home or office.

Thanks!
