Hello all. On my MBA running Lion when I close the lid (laptop goes to sleep), after I lift the lid my Logitech USB mouse won't function. If I unplug the USB receiver and plug it back in the mouse functions again. Please no comments as to why I'm using the mouse and not the trackpad, I like using a mouse. Anyone else having this issue? I have a 2012 MBA running Lion 10.7.4. Thanks.
