Today ,after shutdown the firewall in WINXP,
I run the database on WInXP again,
and the FB event alert act as normal,but
when
IB_Event.unregisterevens;
IB_connection.close;

the following error appear:
EAccessViolation - Access violation at address 10024788 in module
'gds32.dll'. Write of address 01F600E6.

the above error situation didnot happen in Linux.
