Magicprefs with Magic Mouse - problems

Does anyone else have issues with the two finger swipe and using two fingers to zoom in and out on webpages with the magic mouse and magicprefs. I have two finger swipe set up to move forward and back on webpages and I also have the pinch to zoom in and out set up on the magic mouse with two fingers. I find that everytime I swipe back or forward to flip pages on websites, it triggers the pinch to zoom in and out as well (shrinking or increasing the font size); getting pretty annoying. Any suggestions apart from disabling it?
