Dear Jena community

I am starting to use the Jena framework but before I am installing/using
the fuseki RDF server.
I could start and run it properly but with some peculiarities:

1. When started with the mem option (in memory) and some RDF data is
loaded into a graph (no default graph) the only command that runs well
is the s-get with the graph again: All the RDF statements are returned.
The s-query --service is not running - nothing returned. And in the
webconsole http://localhost:3030/sparql.html none of my graphs are
loadable, neither per from <graph> nor by the apposite field "Target
Graph URI". Why is this so? Is there a bug in the fuseki server?
Here my operations:

./s-put http://localhost:3030/ds/data http://semweb.ch/SEMWEB
/Users/fabio/Documents/DATA/thesauri/pp_project_semweb.ttl
./s-get http://localhost:3030/ds/data http://semweb.ch/SEMWEB
./s-query --service http://localhost:3030/ds/query 'SELECT * from
<http://semweb.ch/SEMWEB> {?s ?p ?o}'

2. I restarted the fuseki server with "./fuseki-server --update
--loc=./RDFDATA /ds" and noticed that all three of the commands ran well:
./s-put http://localhost:3030/ds/data http://semweb.ch/SEMWEB
/Users/fabio/Documents/DATA/thesauri/pp_project_semweb.ttl
./s-get http://localhost:3030/ds/data http://semweb.ch/SEMWEB
./s-query --service http://localhost:3030/ds/query 'SELECT * from
<http://semweb.ch/SEMWEB> {?s ?p ?o}'

still the web console "SPARQLer" "could not load" the graph
"http://semweb.ch/SEMWEB";

What is wrong in what I am doing?

Thank you for your advice

Regards
Fabio
