I have the same mouse model. I simply love that mouse and used the buttons a lot in Windows XP. I hope that a solution or an equal alternative is available out there.
I want to ask you if there is something new ?! Have you managed to make it work inside Windows 7 ?!
You say that the Smart X7 mouse driver
version 7.80 works partially for BW-5, is it possible to cut and paste using the two small buttons located at mouse's top middle ?!
Please let me know. Have a blessed day!
