Claude, I see on Thierry's smsq.free.fr site that there is a antialiasing enabled version of ProWesS that might solve the problems with the fonts. However I do not know if it supports high colour and/or if it's compiled with QDOS-GCC... and I am afraid to try :-))) (It took me about a month to bring my ProWesS installation to a usable state and I don't want to blow it :-)
