Thanks for ur reply Shawn, yes the problem did start after I had installed a new driver as my mouse touchpad had started behaving erratically. Once I saw that the snap to function got uncheck automatically inspite of checking it several times in a day, I uninstalled the driver and starting using the native drivers, however, the problems still persists. I then tried installing the drivers that came with the dell laptop with no change in status. I am very used to the mouse snapping to the default button as there are many in my line of work. Its just very irritating that this mouse property doesn't work fine anymore inspite of checking the box in the CP
