Delphi Error

Hi,
I'm using PsqlODBC (v06-40-0007) on a win 98 machine to access data on a
Linux Suse 6.1 Server.

I've PostgreSQL version 6.5 on my server machine and all seems to work
fine. But if I've a Memo Box, and I press more than one time the button
"refresh", the program crash. I've tried to modify ODBC settings and the
system works only if I uncheck "Text as a long varchar", but this limit
my memo fields to 254 chars.

If I uncheck "Text as a long varchar" and increase "Max varchar" over
254 the system crash too.

Can you help me ?

Thanks

Here the logs and in attach the ODBC SQL.LOG

This is the win98 error:
