I am fairly new to Mac, and have a problem with wireless mouse. It does all it is supposed to do except i cannot drag and drop icons or any work done in applications any advice? ....More detail..... once a desktop icon has been highlighted with a click with the mouse, holding the mouse click down I cannot drag the item to the trash can on the dock. Also I am unable to drag and drop any documents to any folders etc. Other than that the mouse works fine. I tried resetting the secondary commands under system preferences. All problems started after restarting the computer after a 13 day shut down because of hurricane Ike. Thanks for help
