I'm sorry if I repeat the same question, since I cannot find any post
about this using the yahoo search.

I develop my application using dbExpress of Delphi 6. But seems like
Firebird client does not support multithreading. Everytime one thread
create new connection, the other thread will fail to create another
connection. Is there something that I should do for this to work ?

The same test application works fine when I change the connection
property to mssql, that's why I suspect that the problem is not
associated with dbExpress or my application.

TIA
