So, here's the story. I turned on my imac one day, and i tried to launch safari by clicking the left button ( primary button ) and it launched expose (which is configured or the middle button) so i kept clicking and clicking i tried the right button ( secondary ) and it also launched expose. By this time i am getting fusterated. My side button still works and launches spaces but left, right and middle only do what the middle button is configured too. I have tried taking out the batteries putting new ones in , and disconnecting it from bluetooth. Any suggestions are appreciated .
