I had 2 connections to the same database, one with SB and Editor windows opened, the other had just an Editor window.
Oracle sessions lost so I used Test connections function in Toad. After that Type tab is not applicable on Schema Browser drop-down list. Also Types is missing on Configure browser tabs option. In the session with one Editor window it works normally after I open a new SB window.
Also the latest beta affected.
@JohnDorlon, I sent you some sample screenshots offline.
