Rod,
I see. This seems to be a serious problem for M$ I am sure they know about it and if the know about it I am sure there is an article about it. I have not run into something like this myself, but I might just have to write an app so I can witness the problem myself.
Do you know if this could be classified as a bug? Is it fixed in .NET 2.0?

What do you mean by re-create the dataset? (I thought I understood but now it is not that clear)
