If you attempted to select several tables in the table list of the MySQL Model view, and you accidentally included the Add Table button in your selection, then a message box appeared warning of an unknown exception:

"Unknown Exception caught in: c:\documents and settings\mysqldev\my documents\visual
studio 2005\projects\workbench\backend\windows\wb.wr\src\Wb.h at line 1010"

The program did not crash. Only the messagebox appeared. (Bug#41201)

If two foreign keys were created in a table that referenced a second table and then an attempt was made to delete the relations and the referenced table, MySQL Workbench crashed. (Bug#41025)

When clicking the + and - buttons in the Physical Schemata pane of the MySQL Model tab, an Unhandled Exception was generated:

System.Runtime.InteropServices.SEHException: External component has thrown an exception.

(Bug#40971)

The Referenced Column pane of the Foreign Key tab became cleared if the foreign key was renamed. Subsequently, attempting to choose a Referenced Column did not display a link in the EER Diagram view. In order to get foreign key relationships working again it was necessary to de-select the checkboxes from the Columns pane, re-select them, and then select the Referenced Column pane. (Bug#40649)

When a table was renamed the inserted data was lost. (Bug#40327)

A complex EER diagram threw an exception whenever an action was peformed on it. However, other diagrams in the same MWB file functioned correctly.

The exception generated was:

System.Runtime.InteropServices.SEHException: Un composant externe a levé une exception.
