Problem with TIBCAlerter

[Joschim]

I'm using Delphi 2009 / Firebird 2.1.2.18118 / Windows XP / IBDAC 3.10.0.15 for RAD Studio 2009

My Application is working very fine with the IBDAC-Components.
Now I use the TIBCAlterter for a event if a tabledata changes.
If I change the data the event will occure but then I get the Error:
Project XXX.exe raised exception class EIBCError with message '
unknown ISC error 0'.
in IBCClasses
procedure TGDSConnection.Check(Status: ISC_STATUS);
begin
if Status > 0 then
IBCError(FStatusVector, True, Component);
end;

What is the Problem?
Thank you!

I can not reproduce the problem.
Please try to use the Alerter demo of the IBDACDemo and check if the problem still exists.
