Thank for all the reply's.

I fixed the first problem like suggested by Geoff, work fine that way.

Well the second problem is a litle more complex so I tried to set up the
same senario with the MasterLink program (one of the demos).
1. First I create a mdiform and make the other form a mdichild.
2. Then I create a datamodule and put the connection, transaction and the
query components on to the datamodule.
3. I don't make any changes in the code except redirect where nessasary to
the datamodule.
4. I change the child form from autocreate so I can create and destroy it as
I like.

This is very much the same setup as in my program.

After all this I have managed to make the order and items datasets not to

If any one has time to reproduce this I would very much like to hear what
came out of it.

Declare the boolean field at the database as NOT NULL. IBO
automatically picks up on this and only allows the true/false states.

Probably need more info on this one.

I take it you must be just hiding the form. When you reopen it there
should be no reason for the datasets to change anything - should
there? Or are you saying that the even when you move records on the
master (after reopening the form) the detail is not following?

This may require a small demonstration app. If you setup the demo
using one of the existing sample databases you can avoid having to
send a database and an application.
