Subject Re: [IBO] More than one Lookup combo to one dataset

As everything one good side must have compromise. I have put 5 queries on
the form for now but I hope to get back to this later and find a better way.
As I have previously played with ClientDataset (MIDAS) I am tempted to
attempt a port to support IBO which would save traffic. Since the table only
has around 30 entries this is not so critical at the moment.

Thanks for your answer, I will look it up in any cases.
