1. Problem Description
        
        In UnixWare 7.1.x and Open Unix 8.0.0, xterms saved in previous
        desktop sessions can acquire privileges they should not have in
        subsequent sessions.

        In UnixWare 7.1.x, xterms saved in previous desktop sessions do
        not honor the value of the LD_LIBRARY_PATH environment variable.
