Q: Imac 5k mouse pointer jumping erratically. I disabled shake mouse pointer to locate in OS X El Capitan to fix the issue but, I like the feature and don't won't to disable it...Help!

unfortunately, none of the above. I like to game a lot and, started using the Razor naga chroma wireless mouse. But, lately that's not all I noticed. I also have the Harmon Cardon soundsticks II which are bluetooth and sometimes live streams and youtube videos start sturtting peoples voices so bad that I have to stop watching and, restarting the iMac is the only way I can go back to watching live streams or videos. The mouse pointer issue usually happens when I'm playing World of Warcraft. I have my character running along and the mouse pointer will jump to the top or bottom of page and spin my character around in the opposite direction shifting the camera angle to looking straight up in the sky. Almost, like I ran into a wall. Once it starts doing that I have to Exit WoW and restart the program. The mouse pointer also jumps around in Os X while I'm trying to click on icons trying to completely exit World of Warcraft. Usually,restarting World of Warcraft fix it for a day or two. I reported the bug to Blizzard but, haven't heard anything from them.
