Issue with TOAD for Oracle 11 Read-Only:
When opening the SQL Editor tab already opened. If you enter text (code) in that tab and run it everything is fine. But when you right click and select to open another Tab in that same editor the application error out and freezes.
If you do not enter any text in the first tab and open an other tab, the application doesn't freeze.
,
Workaround:
Open up a new editor window.

Status:
Waiting for fix in future release of Toad for Oracle Read-Only.
