I'll tell you why not.... immediately after installing and running the Constant Guard Suite I noticed I started having problems with WoW.
My problem was that anytime I tried to type a command (that is ANY key press outside of a message, either whisper, or chat... the quick action commands (numbered 1-=) would be activated!
And, they would be activated in rotation (1 then 2 then 3, etc). I noticed this because I have my attack key slaved to quick action #1. So I would get in a fight and spam the #1 key. Well, my attack went haywire because I wasn't spamming the attack button... I was going through all the numbers in sequence from 1 through =!
I thought maybe my mods were causing it and disabled all my mods, it still happened. Then I though maybe my keys needed to be reprogrammed and tried, anytime I pressed a command key instead of the actual key it would enter the current rotation!
Any way, I thought for a few minutes what I had changed on my computer recently and realized I had just loaded the Comcast Xfinity Constant Guard Suite. So, as an experiment I unloaded it and everything started working fine in WoW!
So.... if you're a Comcast customer and you load the Constant Guard Suite and notice you're having problems in WoW... now you know what is causing them!
