I'm new to both - but used to be competent with Together and Rose.

What version?
I just downloaded the eclipse modelling edition

http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/galileo/R/eclipse-modeling-galileo-incubation-linux-gtk.tar.gz

It's by no means perfect... but it's very good indeed.

It may be worth installing this as a clean standalone to verify your problem?
Especially since....

...works really well for me.

Having done this I can select the association, change multiplicity etc in the
association preferences (or by clicking on the src tag, pressing f2 and
appending "[0..*]" to the tag - nice.
