Hi, so my brother bought me this new keyboard 2 months back for my Birthday. At the very beginning it started making problems because when I press and hold a button, for example W, If I press ANY other button on the keyboard, it stops responding to the W command. As you can imagine, it brings quite a frustration when playing an MMO or an FPS game, where constant button flicking is mandatory. Has anyone got an idea what might be the problem and how could I fix it? It's a plug-and-play, and I didn't find any drivers in the box, the manual was 2 pages long describing the features of the keyboard and how to plug it in(Take cable, plug in PC).
