I cannot reproduce it by just adding more objects to the DS. I think I
had `particular' objs in the journal when I saw it: ie. if I only
push .xo packages to the DS the journal scrolls very slowly (after

I can see similar percentages with spanish (perù) translations ;)

Note that only the comboboxes entries get translated, the timestamp gets
always shown in english.
