Magic Trackpad right click region

I have an original Magic Trackpad. I've always noticed (even without BTT) that if I try to right-click on furthest part of the lower right corner of the pad it registers as a left click. I have to click about 5-6 mm to the left of the corner in order for it to register as a right click. Are there any settings to adjust the click region, or is this just a bug in the design?
