I replied (twice in fact, with example) on this topic yesterday; it
looks like nntp swallowed them...
But as Alvin hints - you need to use the *same* DataSet (or other
model) instance in both forms for changes to be immeditely visible -
otherwise you'll need to do a lot of manual juggling. This could be by
passing a DataSet into the form, rather than creating one per form.
Some hasty re-typing... (below)
