Middle mouse button vs D2

Howdy started all over again and was trying to get my middle mouse button assigned to "swap weapons" in the configure controls menu, am pretty convinced it worked in the past though.

Can u folks assing it, if so I probably has to do with the Win 7 I'm running now (Win 7 seems to install all drivers but never the correct onces that make everything run smoothly)|||You need to run it in compatibility mode for WinXP SP2 for the middle mouse button to work.|||D2 didn't launch at first in compatibility mode but after I ran D2VidTst it worked!

Thanks for the solution
