IBCAlerter and freezing application

[bicman]

IBDAC 3.50.0.17 - Delphi2006 - WinXP - FB 2.1.3
IBCAlerter on Form:
all properties are default + only 1 event 'abc' added at Events property

event 'abc' in DB:
TRIGGER xy FOR file ACTIVE AFTER INSERT OR UPDATE OR DELETE AS
BEGIN
POST_EVENT 'abc';
END

on this form is CRDBGrid with IBCTable (file)

OnFormActivate() Alerter.Start;
OnFormDeactivate() Alerter.Stop;

...and now:
- with IBCConnection to localhost - all work fine
- with IBCConnection to far computer (Linux + FB 2.1.3) - app work fine until activate this form (follow application freeeeeeez)
