Query: No Win 7 or Vista support

I love my two Expert Mice, but when I got a new computer this week I also got this response from Kensington support:"We regret to inform you that, Kensington has no plans to release a compatible Mouseworks software \ driver for VISTA and Windows 7 Operating Systems.The trackball can be used as a normal mouse on Vista and Windows 7 OS and the programmability of the buttons is not possible on Vista and Windows 7 OS."So this has become an orphan product. Too bad, as I don't know of any good alternative.
