[turba] different behaviours

[Red Dwarf]

Hi,

I have a simple question, hopefully there is a simple answer. I have 
setup Horde 3.0 (an upgrade from 2.2), Turba 2.0 (an upgrade from 1.2) 
and an IMP 3 (an upgrade from 2.x)environment.
When I do a search through my address book that I select from the IMP 
menu everything works as expected. But when I do the same search 
directly from the Horde->'Address Book' menu this search failes. Can 
anybody explain to me how this is possible? Are the using the same sources?

Best regards,
Haaino
