It already was.

I also tried setting the CountAccurate to false, as I dont use this anyway
and it still made no difference. The second time I opened the dataset, it
brought all the records again.

It is strange because if you ise a normal DBGrid & IBO it seems fine, and
yet if you use the DevExpress grid and IBX it seems fine.

Theres obviously something they dont like about each other.
