[QUOTE="IWT, post: 1878576, member: 83420"] My thinking on what "zipping" might mean is that the cursor/or highlighted list is caught in a continuous scroll starting at the bottom of the dropdown list, reaches the top and starts scrolling up from the bottom again. Similarly, clicking on the Volume control causes the white circle to move from left to right, then starts again from the left in a continuous cycle. I haven't a clue what is causing this, but it disappears after a reboot, only to return several days later. We must get clarification from the OP. My thought at the moment is that a reinstallation of the OS via Recovery Mode might help, but it's really too early to speculate at the moment. Ian [/QUOTE]
