Editor refuses to open additional tabs

All,

this relates to Beta 13.0.0.26 of Toad for Oracle.

When I drag a file into the editor it will create a first tab to allow the file to be edited.
Dragging in an additional file has no effect. When I click the + sign to open a new tab nothing happens.

When I double-clicked a file in the project manager view a different component of Toad opened up ( I don’t know which one).
Then Toad started having crashes. I was unable to close my Toad session.
Had to resort to windows task manager get kill the session.

After restart issue did not re-create.

For details, please see error log below.

Kind regards,
Abe Kornelis
