Recently, my touch pad will no longer allow me to double tap and drag.  I checked the mouse settings under control panel and the check box next to that option was clear.  I checked the box, applied the settings and exited.  It worked fine.  Everytime I restart the system I have to do it all over again to be able to double tap and drag.  VERY ANNOYING!!  Please let me know if anyone has had this similar problem.  Everytime I go back to the mouse settings after I start the computer the double tap and drag check box is clear.

Thanks in advance!
