I got some problem with Razer Lycosa.

When playing WoW, if I hold down W and A, I won't be able to open the map by pressing M.

But if I hold down W and D, i don't have this problem.

What is happening? Any solution?

After countless experiments and a few Q and A sessions with Razer tech support, I finally got my answer.

It is actually the hardware limitation of the keyboard itself.

So no opening the map while moving slanted for me.

Learned my lesson to not trusting any hardware manufacturer even if it is a company as reputable as Razer.
