You dont need to disconect from the database, when BDE or you starts a
new transaction you will see the new data commited from others. If I
remember right, 4608 will make a consistent view of data reflecting
the database when the transaction was opened.
If you want painless transaction control I suggest you to use IBO
instead of BDE. It does a great job with transactions and still gives
you the power to control them whenever you want.
