I like RC too (although I was more of an ObjectBar guy).
There is only so much development time that can be spent on any and all projects. RC was not the best investment of time . . at the time.
How's about this, ZubaZ, for a possible solution:
Fix RightClick up so it works with 64bit systems - and that's it....
As for distribution it -could- be an unsupported application. Just plaster the download page with a humongous sticker saying
NO SUPPORT AVAILABLE
and direct users here, to the Wincustomize forum. There are plenty of people here willing to offer help and assistance - for free.
As for pricing?
Would 10, 15 or even 20 bucks be a fair/too high price for an unsupported application?
Personally I wouldn't give it a second thought hurling 50 bucks your way for a working RightClick.
(Would be awesome hearing Brads take on this....)
