Hi Steven,

I'll do that tomorrow asap - I need to make sure that my code is still
up to date, which I cannot do from home as my connection is rather slow
now.

Anyway: Meanwhile I had a look at the source code (version 1.42): Looks
like the open character is directed to the stream separately, then the
next item, etc.

Thanks a lot!
Christian
