Up until about a week and a half ago my wireless mouse worked just fine. All of a sudden, the mouse acted as though I had pressed the left button twice almost every time I pressed it. the biggest problem comes with MS Outlook 2003, one left click on an email tends to open it. One left click and drag the email to an inbox or an archive folder to move it, results in weird things, for instance, it may end up in the folder to which I intended to move it, or it may place it some other folder, or it may open a different folder.
Some times it does more than one of these things at the same time. It is almost as though the left button is bouncing or the electronics in acting that way.
