My trackball, which I’ve been using instead of a mouse for several years now thanks to a push from my friend Dave O’Hara and my chiropractor bill started to go on the fritz this week.  It wouldn’t click correctly and sometimes would register a double click (a few times causing me frustration).  I ordered one to come from Amazon to replace this broken device.  This afternoon it seemed toast.  It wouldn’t click, it would just make clicking sounds but fail to actually send the correct signal.

In desperation as the replacement hadn’t arrived I cracked it open and blew it out with a compressed air can.  After replacing the batteries this thing is humming along and working like new.  Except I still have a new one on order.  Anyone looking for a trackball? 🙂
