Cannot Delete Groups in Ecopath 6.2 beta

[keithhg]

I am trying to delete a group in Ecopath 6.2 beta, when I click OK the group does not delete and then windows gives me a warning and the program crashes.

Not sure what is going on.

Below are the details of the Windows warning::::

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

Exception Text

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.

Hi Keith,
Drat, you're totally right. We're on it, thanks for this.

Fixed, bug was caused by a malformed database foreign key constraint
