Hello, First of all, I did search and came up with nothing. Being a new computer, there really isn't a whole lot of information. Basically, I have a new 13" MBP. 2.4Ghz, 4MB Ram, basically a week old. Downloaded and installed WoW no issues until I started to play. My mouse, a Logitech Anywhere MX mouse skips when gameplay starts and basically becomes unusable. This is when I actually enter the realm and I try to walk around and play. When I start WoW and log in, the mouse does not skip, it is only during gameplay. The trackpad works fine. Did some testing, and the mouse skips when it is on the right side of the computer, or the opposite side from the receiver. When I have the mouse on the left side, or the same side as the receiver, the mouse works fine. When I am in firefox or anything else the mouse works fine on the opposite side of the receiver. Just to eliminate the mouse, I started WoW on my aluminum MB unibody, late 2008 model. The mouse does not exibit this behavior during gameplay. So this is specific to my new 2010 MBP. Any ideas?
