I have a project that includes 2 procedures, that use 2 seperate IBO
queries. The first procedure, clears the first query's sql, adds a
new simple 'select * from table1 where' style statement, opens the
query and then does a record count. The second procedure uses a
different query to access data in the same table ie table1. If i run
procedure1, then procedure 2 and then procedure 1 again, I
occasionally get the error access violation in module fbclient.dll
when the first procedure does the recordcount in the second call.

Any any ideas of why this happens?

Thanks
Pete
