Netscape 1.1S version was only released for SGIs, so you'd have to
upgrade all the way to Netscape 2.0.

Hmm. The remote control capability should be there in 1.1N, the
upgrade to 2.0 would only fix problems with relative path names. I
think both of your problems are due to the same fundamental cause (the
system thinks you're using a different browser than the one you're
using), so try the fixes below before upgrading to 2.0.

Is this the problem: when running Mosaic, you can open up 3D files
by clicking on the links in Mosaic, but when you try clicking on links
in the 3D scenes you get the "netscape not running" message?

There's a bunch of variable names in weboogl.perl with "mosaic" in
them for historical reasons. There's nothing in the code that assumes
Mosaic instead of Netscape. weboogl.perl does not have an internal
record of whether you're running Mosaic or Netscape.

The only script that knows is gvgeturl.perl, which uses a hack to
figure it out: it calls "ps" on the browser's PID and checks whether
the name of the process contains the string "aic". If it does, it
assumes you're running Mosaic, if not, you're running Netscape. I can
think of three possible problems:

 1. You're running Mosaic on a remote machine instead of locally. 
    Solution: run it locally
 2. You're invoking Mosaic with some script that doesn't have "aic" in
    the name. 
    Solution: change the patternmatching in gvgeturl.perl

	# bit of a hack, but should work under both SysV and BSD. 
	$psreturn = `ps -ea | grep $browser_pid` if ($browser_pid);
        if ($psreturn =~ /aic/) {
                          ^^^  change this to the string you need
 3. If all else fails, you could hardwire the code to always run
either Netscape or Mosaic, just change the "if" condition to "(1)" to
get Mosaic all the time or "(0)" to get Netscape all the time:

	# bit of a hack, but should work under both SysV and BSD. 
	$psreturn = `ps -ea | grep $browser_pid` if ($browser_pid);
        if (1) {
	    # bunch of Mosaic control  code ...
	} else {
            system("netscape -remote \'openUrl($url)\'");
        }

The prototype is not yet ready for distribution. I am probably going
to continue working on the system, eventually I hope to have a usable
tool. 

Hope this helps,
