I recently bought a new flat screen display for my main machine at home (here’s my original post on the monitor). It’s still great and I’ve definitely become used to it now to the point where it’s normal and all of the other monitors I work on are “small.” There is however one thing that’s been driving me crazy and I finally realized what it was.

It turns out there’s a rectangular dead zone on my desktop where the mouse fails to register/trigger any events. For example, when I have a browser window openĀ and I click on a link that happens to fall into the the dreaded dead zone I get nothing. The link never gets followed, my mouse pointer never changes to the little hand, etc.

My theory is that it’s a driver issue and not really a problem with my display. Though I’m struggling a little bit to really nail it down as it’s quickly becoming one of the most painful bugs I’ve tried to figure out in a while.

I ended up writing a quick little C# program to really prove and demonstrate the location that’s dead and I recorded a video of it to better demonstrate what I’m seeing. I originally tried to record the video of the full-screen but CamStudio wasn’t doing well with recording something at the 2560×1600 resolution so I ended up recording just a subset of the full desktop (somewhere between 1/6 and 1/8 of the entire screen) but it should still clearly demonstrate what I’m talking about.

If anyone has any clues as to what this may be, please let me know. Here’s the video for all to see:
