on your mighty mouse? I've had mine since november and it's worked perfect since then but lately it hasn't been scrolling down all the time. I tried spraying canned air in it already and that didn't work... I remember I saw a thread on using a piece of scotch tape a while back here to clean it without taking it apart? I'm not mechanically inclined enough nor do I want to manually take the whole thing apart and have to glue it back together and ghetto rig my 70$ purchase. Thanks.
