Default browser for 'message URL' hyperlinks

[Steve Rickaby]

This is a *Mac-specific* question which we've bandied about on the FmforOSX group for a bit, with some interesting insights but as yet no solution.

For some reason, my FrameMaker 7 installation has become obsessed with using Netscape when web hyperlinks are control-option-clicked in a FrameMaker document. I have some archive disks attached to this machine, and it managed to find a copy of Netscape 3 (don't ask!). When in desperation I killed Netscape 3, it then went off and ferreted out a copy of Netscape 4.7 that was sitting in backup disk copy of a friend's Mac that I'm made for them.

In all cases the default browser setting for both Classic and OS X is Safari.

Does anyone know how FrameMaker selects the browser to use for web hyperlinks, and how to configure it? I cannot find anything in the user guide or online help (which sometimes opens in Safari and sometimes in Netscape).

With thanks in advance.
