My take at this point is that xmosaic-2.pre4 has hardcoded "-home" command
line option, for obvious reasons (NCSA folks, can you verify this ?). As a
result, ss-1.2 ignores the first slide in the URLfile as home_page and hence
not seen at startup. This problem is not seen with older robust versions of
xmosaic. If and when xmosaic-2.pre4 becomes robust release4 things should be
back to normal.
