When click mouse, doesn't work properly; it draws a rectangle or moves icon...
I have tried 3 different mice (Apple, Kensington and Logitech; 2 with USB connection and onebluetooth) and all malfunction the same way with my MacbookPro. When I click the mouse, it draws a rectangle and then when I move cursor, it just changes size and location of rectangle. When I click on an icon, instead of opening it, it highlights it and moves it around the screen. The mice work fine with another computer so it must be a software problem ??!!
I have tried repairing permissions and have verified disk via Disk Utility but nothing helped. Would appreciate suggestions.
MacBook Pro, Mac OS X (10.6.7)
