Hi Jr,
in this case I would try to hack it in the GsInitialize function in
srvmain.c.
I think this is the position where the root window is created. It should
also
be possible to do it the same way than in the example I wrote. You
should try
to find out what functions are called by the Gr.... routines and use
them in GsInitialize.
But ts a good idea to show a picture instead of a blank screen. What
about the running cat
of the microwindows webpage?
cheers
