Okay, everything has been fine for 9 months, then suddenly when dragging an icon, it will shoot left and right of the cursor. Also , its shadow when dragging would disappear - then reappear! Finally, if a desktop window is dragged anywhere it snaps back to the left or right of the monitor. The drive has been completely reformatted followed by a reinstallation of OSX, then the problem reoccured. Any inqueries?
