************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

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

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Sometimes I see strange error message: 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

Program is useless with this errors. HW: Thinkpad Z61M, 3GB RAM, ATI Mobility Radeon X1400

How to repeat:
Double-click on table in EER Diagram

Many thanks for writing a bug report. Unfortunately, we can't reproduce this behaviour.

How did you start Workbench OSS? Did you start the software and then opened your diagramm or did you jsut click on the diagramm?

I tried both. I tried also restart computer, repair and reinstall product, but this behaviour still remains.
But when i first installed workbench, everything works fine. I created EER model, drew some tables and relations and after that, workbench starts strike :)

Today I created another model, and also import some models from sql create script and workbench goes without error, so i suppose error is in saved file. If there is a discreet way to send you file, i can do it.

There is one more step i provide on faulty model. After installing workbench, there was undo history set to 0. I saved model and then set undo history to 1 (workbench goes very slowly) and again saved model.

A similar behavior is reported in this bug.

Try disable "reopen automatically" if is checked.

Bye

it was`nt checked.

Many thanks for your feedback. We are still fishing in the dark here.

You file would be a great help.

You are able to upload your file here:
http://bugs.mysql.com/bug.php?id=42093&files=1

When you will set privacy to: Only developers will be able to see the file then only the MySQL employees with special rights are able to see it.

Also of course you can use our FTP to upload the file and let us know the details (like filename you uploaded) here as a comment set to: "hide comment from public".

Comments that are hidden from public also only the MySQL employees with special rights will be able to read them. The same with our FTP server. Only this employees have access there.

No feedback was provided for this bug for over a month, so it is
being suspended automatically. If you are able to provide the
information that was originally requested, please do so and change
the status of the bug back to "Open".

Many thanks for the feedback.

Unfortunately, because you didn't change status to "open" our system set status to "no feedback".

Anyway, your issue is not repeatable here.

Please try Workbench 5.1 and let us know if you still run into this problem.
