My screen has a dead "click" zone(invisible window)?

Question

The weirdest thing is happening to me - there is a dead zone on my screen where I can't left-click up on the right side of the Screen. On SO, it covers parts of the toolbar. I can click the left two-thirds of my profile link, but not the right 1/3, and I can't click on the inbox icon, trophy icon, help icon, or stack icon. I also can't click on the right side of the higher hot meta posts. I also can't even close this window normally - the minimize, maximize, and close buttons won't work. If I have an internet tab over to the right, I can't close it.

However, I can RIGHT-CLICK in the dead area, and when I do, it says "CTRL+C," but greyed out.

Is there an invisible window up or something?

Answer 1

I added a second screen, and the box vanished. I then went back the original screen, and it was fine. Maybe the effect from https://xkcd.com/1479/?

Answer 2

I've also had this problem recently on my monitor at work. I get a dead zone in the bottom right hand corner of the screen. The dead area is about the size of the Windows notification area that slides out.

I already have dual monitors, but it only happens on one of them. I've yet to figure out what causes it, or what it even is.

The only way for me to get rid of it, is to restart the PC, or go into task manager and restart the explorer.exe process.

Update: Turns out explorer.exe would only work for me sometimes. The easiest solution is to press the power button on the monitor to turn it off, then back on again.
