Hi, I'm having a problem with the pro mouse on my son's iMac. It's a G3 runs os 9.1. Blue coloured. When it's switched on, the mouse icon on the screen does not move, pick it up and the light flashes for about 10-15 secs then stops, mouse then works for about 5 secs then stops completly. Can it be fixed or does a new mouse need to be bought, it's a sealed unit, cant get into it. Customer relations at my local comp shop is appalling, not getting anywhere, so thought i would try here. My son has learning probs and imac is brilliant for him and he is desperate to get back on. Can somebody please give advice. Many thanks.
