Just after some advice, and hoping some of you can help. I've just bought a new iMac i7 27", and have installed windows 7 with bootcamp. I'm left handed, so I want to swap the left and right buttons on my magic mouse around (in windows) - pretty simple. I've gone to 'personalise' and clicked the box to change the buttons around, however, as soon as I clicked it, it changed both of the magic mouse buttons to the second click function (right click on a normal mouse configuration). I had to then use the keyboard to tab through and untick the box before I can use the mouse again. Basically I would like to know (a) why it's doing this and (b) how to fix it! 
Any ideas?
