ok, I made the mistake of buying a betson imperial 3" trackball instead of happ's. now I can't figure out how to hack it through a mouse. does anybody know how to do this? there is plenty of info on how to do the happs, but none on the betson. any help would be appreciated. also, the hagstrom and Ipac both have encoders that will handle happ's trackballs, but what about the betson? can they do those too?
