Something comes to mind, if you have something in the OnError event
somewhere that is suppressing an exception being raised this can cause a
real problem.

It is rare if ever that you want to suppress an ERRCODE coming from the
server. You should either allow the default exception to be raised or for
sure raise your own unless you know VERY well what you are doing, which
means you and I will have had a conversation about it first.
