So I've had this annoying issue with my Z key where it sometimes stops working... Even after I bought a new keyboard. Its a bit of a strange problem so bear with me while I explain it. First off, this issue just comes and goes and I can't seem to tie it to any process. When I press the Z key without any modifiers (i.e. shift, alt, ctrl) the key refuses to show. But once I hold shift, caps Z shows up fine. If I put on caps lock, just pressing the key won't work either. I have to press shift + Z for a lower case Z. Another thing which I find strange is that if I set the Z key as a shortcut on its own, it works fine. It seems the key just won't show :/. I did full tests with Nod32, Ad-Aware, Spybot and they've all come up empty. I'm totally enjoying the new keyboard though.
