[JavaScript] peculiarity of onselectstart

Mon Jul 14 10:01:20 CDT 2003

Actually no, I hadn't -- I had presumed that this event handler was
"global", and that the bubbling was implicit in the top-level document.onselectstart
declaration at the beginning of the app window.  Any notions as to the
"correct" style/placement of these mid-stream event blocks that won't impair functionality
above/below the object under consideration?
