thanks for the report - bugs will be fixed in the next snapshots. I would have
tested my changes, but unfortunately I did not have any test harness, was to
lazy to create some myself and trusted in my programming abilities too much
(although my little good programming angel cried out in horror). Could you maybe
send me one of your ui files having such a custom widget?

best regards
