I have just installed Toad for Oracle 10.5.1.3 "Toad for Oracle 10.5.1 Commercial.exe".
On some packages and procedures, I get an error when using Code Road Map.
When right click on a Package/Procedure | Code Road Map
A screen, [Please Wait...], pops up with message "Updating Diagram ... Loading Graphic".
This screen just hangs there for ten minutes and finally errors with:
"There was a failure when loading database objects into the diagram!
ORA-00933: SQL command not properly ended"
Code Road Map worked on 9.6.1.1 on the same package procedure.
