Hi Efe,

hmm, so I think most of the work in FillItems seems redundant, I
wonder if there is another listbox subclass that is better suited for
this kind of usage (Caolan, in Cc, might know).

Failing that, let's look into dynamically updating the content (either
stick 100 items into the listbox, then reschedule, or make use of this
SvListView concept - FWICT, that should allow you to show items from
your own internal container on demand).

HTH,

-- Thorsten
