First of all, excuse me for jumping into this discussion all of the
sudden, but I couldn't resist. Being one of the members of the former
Erwise-team, I have some ideas about X-browsers (Erwise is a Motif-based
www-browser, implemented as a student project at Helsinki University
of Tech. during 91-92)

Well, unless we'll be seing >32k*32k displays in the near future, it's
not that bad.

Erwise works correctly ;)
Actually, doing the scrolling by hand (even in an optimized way) isn't
that hard, you might want to take a look at our code (available at

Yes, I know, the code is something of a mess, especially since we
hacked a bit on the common code to get non-blocking transfers working
(it's nice to be able to retrieve multiple documents at the same time
and read through the ones on your screen, though).

Hmmmh, no offence, but I think that's not not the correct way to solve
the problem.

Btw, have the current x-clients implemented non-blocking transfers?
It should be implemented in the common code, maybe it already is. It's
really too bad that we don't have the time to support erwise (three
of us are working almost full time at a software company, and try to get
on with our studies as well). Maybe in the summer ...
