DBLookupComboBox .. Stuffed

Hiyas,
     I'm having a few hassles with a DBLookupComboBox ... it seems to show
the selection (one of) ... but every time I hit the button the list wont
come down ... it might just be my delphi, for some reason I keep getting
errors in pasdbk16.dll (or sumf'n like that) ... <sigh> .. how can I make
this work ??

Exie.
