************** Debug JIT **************
Per attivare il debug JIT, è necessario impostare il valore
jitDebugging nella sezione system.windows.forms del file di configurazione
dell'applicazione o del computer (machine.config).
L'applicazione inoltre deve essere compilata con il debug
attivato.

Ad esempio:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

Quando il debug JIT è attivato, tutte le eccezioni non gestite
vengono inviate al debugger JIT registrato nel computer,
anziché essere gestite da questa finestra di dialogo.

How to repeat:
Create a new view, select it with double click and than delete the view. When trying to do anything else: "System.AccessViolationException" pops up and than WB hangs and is closed by system (after a god's sake "save").

Thank you for the bug report. Could you please test with latest released
version 5.0.17a. I was not able to repeat the behavior reported. Thanks
in advance.

well, before uninstalling 5.0.16: create a view in an existing diagram with tables, delete it from the EER Diagram via right-click menu; double clic on any other object (e.g. a table), Access Violation!

new version 5.0.17: seems OK (couldn't replicate);
[8 Apr 2008 16:05] Johannes Taxacher 
this issue has been fixed in release 5.0.17 RC
[10 May 2008 23:56] Paul DuBois 
Noted in 5.0.17 changelog.

Creating a new view and then deleting it caused a
System.AccessViolationException.
