Hi Terry,

Sorry, you seem to be shifting the thread in the other direction. The saving code is fine as is and it's actually my colleague's. My question was is it an expected behavior or not? In other words, once the table participating in transacton being updated using tableupdate it can not be opened until the transaction is ended. If this is by design, so be it. But if it's not the right behavior, it must be a bug.

So, could you confirm or decline the same behavior?

Thanks in advance.

If it's not broken, fix it until it is.
