Do you mean your code is deliberately swallowing exceptions?

Installed WinXP SP2?

Others (non IBO) are reporting event problems after installing SP2. Is

Is the client remote or local and, if local, how is it connecting? (protocol).

If not this, what kinds of things have you done recently that might have
changed some conditions?

What database and version?
