Several weeks  ago my mouse started highlighting entire words,  or everything on the page.  Wireless mouse I have been using for 2 years. I tried a wired mouse but the problem persists.  I have updates all drivers,  uninstalled and re-installed mouse,  keyboard,  changed settings in mouse controls,  made some adjustments to mouse registry but nothing helps.  I have just noticed the touch pad does the same thing.  It is driving me crazy and makes working on the computer a PIA.

Thank you in advance for any help
