Steve,
A complete example, rather than a snippet, saves me a lot of time.
I've tried to add your stuff to an example we already had, which
wasn't too hard in this case.
It's now test/Xm-2.0/combobox/test14.c .
Your assignment of visibleItemCount is weird. I would expect
to set it after adding the items. But on the other hand it shouldn't
be a problem. The fact that only one item is shown appears to be a bug.
I don't see the other problems :
1. The list is sufficiently wide.
2. I can dismiss by clicking outside the list, e.g. on the
combobox's arrow.
Does test14 show these problems on your system ?
