Mmmh.. so OpenURL isn't included in OS4 by default... at least I get "Cannot open openurl.library!" on my default OS4.1FE setup. I noticed once that there is a URLOpen command instead, and some URL config in the Prefs drawer.
I've forgotten to ask that should Hollywood be using this URLOpen thing on OS4, which seems to be default? I don't remember seeing any requirement for the OpenURL library in Hollywood documentation either...
I've now made my own p_OpenURL() function to check for OS4/URLOpen in my code, so my programs will work on default OS4 installation, but of course it would be nice if Hollywood's OpenURL()
function would just work out of the box too.
