I am trying to connect to a database in the Oracle Explorer: Database section of the Activity Bar and I don't have the password saved for the connection. The "Enter password" window flashes briefly and closes before I can put in my password. If I save the password in the connection information, I can connect just fine, and if I execute a query in the editor, the password window comes up without a problem.
This behavior does not appear in 19.3.1. I do not see any error messages in the Oracle Developer Tools output window.
