Hi,

since you don't give any details about what your application does, I think
what you should do is uninstall Interbase and try whether the same error
happens in Firebird 1.02. Download here (from the firebird-win32 section
near the bottom of this page):
http://sourceforge.net/project/showfiles.php?group_id=9028

The error most likely has nothing to do with IBO, so the support list to use
would be ib-support@yahoogroups.com.

Cheers,
Tobias
