Just a few minutes ago, my laser mouse began to 'scratch' as I moved it over the pad and, when it did, the cursor stopped. On closer examination, I discovered that the little plastic cover over the laser was broken into two pieces. (Don't ask me how. The mouse has never even been dropped on the floor.)
Anyway, a shake of the mouse and the two pieces fell out onto the mouse pad. The mouse is working again, but I'm concerned about the lack of a cover over the laser. Is it safe to use or should I chuck it and get a new mouse?
