We have scripts that look for netscape and connect to them remotely using the -remote command line option of netscape as documented in: http://www.netscape.com/newsref/std/x-remote.html. With netscape 6 what happens is that the browser gets started by default. The -remote option is not described when netscape -h is invoked. The exact command line option used is: netscape -noraise -remote "Edit". This does not bring up the composer/editor but instead starts up the browser itself.. This works in netscape 4.7x..
I think this should be fixed at bug 11185 Adding Blizzard to this bug to verify.
