The only thing I can think of is to go to your Windows mouse settings and make sure the middle mouse button is set to Middle Button or something like that. By setting it like that, it let's the app determine the function of it.
I tried that first, and it didn't fix it. So, I just thought of switching to an older model mouse and everything works perfect. I think the problem lies in my newer mouse wheel having the option of buttons assigned to the left / right action. Thanks for the help.
