I'm not sure if this is the right forum and I'm also not sure if what I'm gonna describe is the real issue, but this is my best guess.
I'm using the Logitech G13 and the Razer Naga for WoW. Sometimes when I spam buttons in-game, everything gets messed up. Some of my buttons won't work at all and some have a different behavior when it happens. This issue is then also present when I go back to my windows desktop. For example, when I press "D" on my keyboard in-game, it immediately beams me to the desktop. When I press "F" on my desktop, it opens some "search window"... I cannot write any text any more, as all my keyboard buttons behave differently.
Normally this happens from time to time, in-game, but if I want to reproduce the issue, I can do it pretty fast... I just have to mindlessly press a lot of buttons simultaneously on my mouse and the G13 and it will happen in a few seconds. I was unable to find out why this happens and why some in-game commands can mess up how windows behaves in general. My guess is that I hit some Win command or shortcut that changes everything, like "alt+shift+x+y" or whatever. I have to reboot to get rid of it.
I'm using Windows 7 Ultimate 64 bit.
Razer Naga in "Num-mode".
Logitech G13 where I have assigned the following keys to it "123456789´qertyuiopfghwasd" and ALT and SHIFT.
Any guess what the problem is or could be?
(btw. for some other reason I formatted my PC and installed everything new, including Win 7 but the issue is still here)
