Hi

I have fixed the problem from my previous posting by changing the
query.recordcount to code that uses a 'select count(*) from table1'
sql code, as suggested. However the problem now occures on a
table3.active:=true; statement. The problem is 100% repeatable but
only on 1 sequence of events/procedures that involve several queries
and tables being activated/deactivated and a 'post'. Change the
sequence and everything works fine. I am stuck at tracking this down
further. What kind of thing causes this 'access violation in module
fbclient.dll' error?

Many thanks for any help given
Pete
