I just upgraded from Delphi 7 to Delphi 2005. I am using IBObjects
4.5.B. When a certain form was freed it executed the

else
Text := '';

code in procedure TIB_CustomerCombo.SysDataChange. This caused an
access violation.

I changed the code to:

else if Assigned( OnGetDisplayText ) then
Text := '';

and don't get the av anymore. This would seem to be a bug.
