Equipment: macbook pro; leopard (up to date); apple wireless mouse +/- touchpad
Problem: operation of both the mouse and the touch pad has become intermittent... suddenly, not gradually. Even when the cursor can be moved, clicking doesn't work (on touchpad, this goes for the thumb panel, too).
Tried: replacing batteries in wireless mouse with AA instead of rechargeables (although those have always worked before); turned off wireless and removed batteries to eliminate cross interference with touchpad. Shutdown and rebooted countless times.
Thanks for helping, especially to all those who might know the fix.
