Possible bug at end of range + minimum range size

[FrizzTheSnail]

Specifying a range 0-24, the thumb stops at 22, and can't pull it up to 23.

The other issue is: how to set the minimum range size? It seems to be fixed to 1. I'd need to set it to 0 so that the thumbs could be fully overlapped.

Thanks a lot, David

Hi. I'm also interested in the same issue. Is it possible to have a range of 0? Thank you.
