I have Windows 8 Enterprise x64 and a Razer BlackWidow Ultimate 2013 Edition.
I am using a Dell XPS 9000.
Whenever I leave my computer alone for a short period of time while it is locked, about 80% of the time one of two things happens.
1) My windows key gets stuck which means that when I type the 'u' in my password the computer starts the 'Ease of Access' functionality of the start up menu. In order to solve this, I have to hit the windows key a few times and then it starts working normally.
2) A key is repeated infinitely in the password field. In order to solve this I have to unplug and replug my keyboard. Then it works as would be expected.
Neither of these two things happen if I lock my computer and then immediately unlock it. It is only when I leave it along for a period and the screen turns off. I have tried the simple things already (reinstalling the driver, evaluating my macros, etc.) but I really can't figure out what is going on. Something similar used to happen with my old Logitech keyboard as well but I can't remember the details. I would really like to get this fixed but it just doesn't seem very clear what is causing the issue. Any thoughts?
