hmm, so this _is_ working with 2.4.22ctx-17c?
which patch of vs1.20 did you try, the one for 2.4.22
and the 2.4.22 source or the one for 2.4.23?
did you use the _same_ config file as for the
2.4.22ctx-17c?
did 2.4.22-vs1.00 work for you?

if you used the 2.4.23, could you try with 2.4.22+patch
and if this works, 2.4.23 without patch?
could you try 2.4.22-vs1.00 with the same config as
2.4.22ctx-17c, and see if it works?
I will try to reproduce ...
there should be no difference in behaviour between
2.4.22ctx-17c and vs1.00 ...
TIA,
Herbert
