So, for the past month or two my NumLock will randomly while I'm using the computer, but I can't pinpoint what is causing it to turn off. I'm using a Razer Blackwidow keyboard and a Naga as my mouse, and all drivers are up to date. I don't have numlock macro'd to anything in Razer Synapse. I don't accidentally push the numlock key. I'll usually notice it after alt tabbing from somewhere else back to WoW, when I'm trading inks at the ink vendor and use my keypad.

So, I was wondering if anyone knows of a Windows Event that is fired when NumLock turns off/on, or another way for me to figure out what exactly is causing NumLock to turn off.
