   wglMakeCurrent leaks on ATI cards - FINALLY it's fixed
  Great news, after installing the Catalyst 5.11 the wglMakeCurrent stopped leaking memory on my systems with ATI cards, the issue which I know existed for several years. I wish it took them less than several years to do it :(for those who want to test whether this is true for their setups - here's the code + binary: download site
  Now this is interesting, it sure returns ati cards another plus they were missing before, which will definetly play big role when i'm buying a new graphical card very soon.
