I have more information.
I went to the apple store and another magic trackpad did the same thing.
I rebooted in the recovery options (which I assume is even more basic than booting into safe mode) and it still does the same thing.
I also happened to have my gmail web page open and noticed that if I am at the top of an email and swipe from right to left in the first inch of the trackpad it will open / close that email if there are other emails as part of the chain.
This seems to be some kind of swipe gesture detection, but that means it is really basic because it also works in the recovery mode.
This does NOT happen from the LEFT side of the trackpad.
I also notice that the same thing seems to happen in the built in trackpad of the macbook pro it is connected to, but instead of being the whole right 1 inch it is about the first quarter inch of the built in trackpad.
I couldn't find any settings anywhere that relate to this type of functionality.
Can someone tell me how to turn this off?
I don't like it because I use the trackpad on my lap and my fingers are mostly on the right side and I am constantly not able to move the mouse without moving my fingers closer to the middle which is not comfortable.
