Latest version of openbox works for me on amd64.
Arches, please have at it. Thank you! (Note: 3.6.1 does not have arm64 as a stable keyword, and I don't know if there is a historical reason for that, but if there are any issues with it, it can probably be safely disregarded (depending on the issue of course).)
