1/2 of the klicks don't work. only occurs on actual map, not the minimap

it might be hard to understand from this gyazo shit, but u can see from there that some clicks are skipped. I was constanly clicking, for sure.

When i spam clicked in one place, about 1/5 skipped.

another, better proof: http://gyazo.com/5394f0c9f93f472b19308e062c040feb

my mouse is fine, 100%. This problem is only in emps, and its frustrating.
