My 3d connection space explore space ball no longer works, It says it's a discontinued product (which it is) and they don't even have an archived driver for it to work. Let me correct myself, it works, but the buttons are no longer programmable, so not really working. Just got a new 3d connection space mouse pro, now it works like a dream. It sucks to throw away a perfectly good unit just because there are no drivers that work, I even had all my archived drivers stored on our shop server, and went thru every one of them with zero success. The amount of time I spent on this last week trying to get it to work, I could have gotten 2 new space mouses.
