At times, the Tab randomly stops working. Once I restart the computer it's working again.

Has anyone seen something like this before?

I'm using a TypeMatrix keyboard.

What happens if you plug in another keyboard or use the onscreen keyboard? – Not Kyle stop stalking me May 21 '12 at 18:14
Didn't know there was an onscreen keyboard. I like that. That's useful for testing things. Thanks! – Ben_Coding May 22 '12 at 20:26

Maybe the keyboard is getting faulty. How old is it? Do you press tab a lot? I know that keyboards are very resilient, my daughter beats on mine daily, but they do break. I agree with Kyle, try using another keyboard to see if that fixes it.

Restarting Windows actually did the trick. Something with this specific keyboard though. – Ben_Coding Aug 14 '12 at 15:25

Some other causes of this issue have been identified:

  • KVM Switches
  • Synergy (keyboard and mouse sharing with multiple computers over the network)
  • Windows thinks some key is stuck: try pressing Ctrl and Alt
  • StickyKeys is enabled: try pressing the Windows Key twice to turn it off
  • Xerox Printer Drivers (Xerox Job Tracker, Xerox PrintingScout)
  • Logmein, TeamViewer, Citrix XenDesktop
