In the STAR WARS hype. "Luke use the Force"

Your playing with the different buffering and disaster is awaiting. Just my opinion, but it sounds like your going to get bit.

I recommend the use of views for upgrade to SQL Server capabilities.

Sounds like it's just SHOW data, and not EDIT data.

It means I've got a live table buffer which I have to revert before leaving the form or executing a requery. And I've got other buffering for new detail items happening on this same form. I'm unsure about how these buffers might interact.
