My trusty 'apple pro mouse' for my iMac died. I think it was somthing to do with the cable. Anyway i got myself a new mouse at my local apple store...this mouse is only a plain 'apple mouse'. I now seem to have this problem with clicking. On my old mouse it had this height adjuster thing on the base of it and i really am not pleased with the new one that doesn't have that and it feels like sometimes the mouse get stuck half way through the click. anyone have an words of advice or comments on this.
