Hi Enrico

We are using the IBO stuff through our app and had the Boolean problem
initially. I didn't even know about the 'FieldEntryType' stuff. What
we did was.....

Open every DM (100+), Ctrl-F12 to view source, search and replace
TBooleanField with TStringField, Ctrl-F12, Save and select 'Yes to
all'. Although it sounds slow, it only took a few hours (tedious ones)
and it works great. Some code still accesses these fields as .AsBoolean
but that 'just works'. I would give it a go :)

As a question to others, Are you saying that is you have persistant
fields, which don't exist in FB opening a table will be slower? Or am I
misunderstanding that issue?
