No answers, only questions.

What is the connection string?
When you say "attempts to insert a new record" what are you talking
about? Does it occur when a dataset goes into Insert mode or when the user
tries to post something? or under some other condition?

Do you have GeneratorLinks set?

What appears in firebird.log when these crashes occur?

In the case of the AV in ntdll.dll, have you checked whether this library
is actually present in the system directory of the Win2K machine? What
service pack level is the Win2K machine on? (Google for ntdll.dll, as I
recall there was a problem with it from one of the service packs).

In the case of the Win98 machine, are you sure that msvcrt.dll and
msvcp60.dll are installed in the windows directory?

In all cases, are you sure that you have the correct gds32.dll installed in
the system directory (windows dir in win98)?
