Ah, ok... Now I understand the code and I can see how stupid was my
comment ;-)

that works for me too, but
./rve -f 25 -s 80 -y 10 -x 50 540 60 0 hscroll_text "`perl -e 'print "$_
" for (1 .. 600)'`" -s 4 > /tmp/rve.fifo
(everything in a single line; sorry if the mailer truncated it) fails...

I did some more investigation, and I think the problem is due to an
overflow in Effect_move::run().
Because of such overflow, _distance becomes negative, and this creates
the problem (in Effect::animate(), t_timer is positive and t_schedule is
negative... Thus, rve wants to sleep for a very long time! ;)

I am trying to convert _x1, _x2, _y1, _y2, and _distance to long long
int, and see if this helps...
