I have a Razer Blackwidow Tournament Edition keyboard, it is cconnected to an Asus X555L laptop, when I play Starcraft 2 the SHIFT key sometimes stops working, when I use it frequently (ex. when I want to queue some buildings with protoss or when I want to inject my hatcheries with zerg). I tried in MS Word and it is working well at normal use, but if I start spaming it, stops working as well, after a few seconds it is working well if I don't spam it.
Thanks.
