Revision 1.97: download - view: text, annotated - select for diffs
Fri May 23 13:56:39 2003 UTC (21 years, 7 months ago) by www
Branches: MAIN
CVS tags: HEAD
Attempt to fix quadruplicate bug 1178: when using browser URL field of
main content window to go to an external site, JavaScript security model
disconnects all access the Remote could have to it, including the one to
even find out if it has access.

Implemented flag "noclient" in the Remote which gets set in an unLoad event of
the main window (ignoring the fact that unLoad is kaputt in some browser
versions).

This all seems to work great on Mozilla, but I am sure there will be stupid
side effects in some odd scenarios.
