Cannot connect with saved Oracle proxy connection info. Error "Invalid username/password" . (4231796)

Toad doesn't save the connection information correctly when working with a proxy connection setup.

Sample:
ALTER USER scott GRANT CONNECT THROUGH test_user;

Connect in Toad Data Point as my_username[proxy_username]/test_user. This connects.

Disconnect then try to double click and reconnect through the saved connection in Toad. It errors out

"ORA-01017: invalid username/password; logon denied"

Looking at the properties of the saved connection, it shows that the user/schema name saved as the original user name, "proxy_username", not the proxy user, "my_username[proxy_username]". 

WORKAROUND:

None

STATUS:

Fixed in version 3.4 of Toad Data Point. The latest version can be download from the Support Portal.
