RE: when to bind *down-mouse* vs *mouse*?

    It's not "(to work correctly on problem platforms)".
    It's because we actively want to support the possibility of doing

         press-button move-to-menu-entry release-button

    in addition to

         click-button move-to-menu-entry click-button

    AFAIK, allowing both behaviors is standard in 99% of the
    toolkits nowadays.

I take that as an endorsement of guideline #3, with an amendment to the
rationale.

What about other people? What about other guidelines? What about documenting
this for users?
