I'v had this BSR infrared mouse model TW500 for some time now but have been unable to the middle button to work in any Windows version. I tried drivers from 3.1, 95, and 98 including ones for Logictec with no seccess. I search the web for the company but I do beleive they are out of buisness. If any one out there has one or can tell me a driver to use it would be helpful. Thanks for your time with this headache.
