When it first happened I didn't have any Razer software or drivers on the computer. I have Windows 8.
The issue is it essentially uses the keyboard buttons, so if num lock is enabled, it works fine, but with it off, it instead uses arrow keys, page up & down, etc. I e-mailed Razer support and they told me to download Synapse, and firmware. I just did it, didn't help. I'll e-mail them back and post any solution I find in this thread. If anyone knows how to fix it, that'd be greatly appreciated.
And bignazpwns, I'm afraid I don't raid at all. I'm flying in the Vale of Eternal Blossoms right now, and I have it completely maxed with 8x AA. I also use a lot of addons. I'm sitting at 30-35 FPS here. In Orgrimmar, instances etc I hover around 50-80. At most, I get like 150. I have the i7 3630QM, 8GB RAM and a 7200RPM HDD.
EDIT: I can't use the number mode because I use those keys for other binds, I have a lot and need a lot of buttons. I'm not sure as to what the cause is, I'll plug in a keyboard and see if it happens, because it doesn't on my rig.
EDIT 2: Nope, didn't help. Starting to lean towards a Windows 8 or laptop issue, since it works fine on my proper computer. I'll try it on my netbook.
EDIT 3: Odd, same issue. It runs Windows 7 so it pretty much has to be the Naga.
