Error connecting to postgres 7.3.2 - Mailing list pgadmin-support

Hi,

I'm using postgresql 7.3.2 on Redhat 9.0 and pgadmin 1.4.12 on windows 2000
and windows 98.
On both systems I receive some memory error when I try to connect to
postgres.

win2000: The instruction at "0x20302e38" referenced memory at "0x20302e38".
The memory could not be "read".

I tested odbc connection (linking some tables with MS Access) and every
thing was OK.
But with pgadmin even "Connection Debuging Tool" fails

Any help would be apreciated!
