Re: Microsoft Access 97 Stores Database Password as Plaintext

[ews () RSMARTINC COM (Ernie Souhrada)]

I just tried to duplicate this, as some of our products rely on MS Access
97, and it'd be a useful thing to know about, and I couldn't do it.  When
I follow the procedure below, I get to step 8 where I'm to select the MDB
that I've put a password on, and instead of giving me a list of tables to
select from, it asks me for the password to the MDB.  Can't get past that
point to get to step 10.

Anyone out there have any luck in making this work?  I'm using Access97
SR-1 on NT 4.0 Workstation SP4 (128-bit).

TiA...
