[Brian Erickson]

When I click on a cache and then close the pop up window - I get an error :

Unhandled exception has occured in your application. If you click continue the application will ignore this errorand attempt to continue. If you click Quit the application will close immediatly.

Object reference not set to an instance of an object.

Here are the details from the error window:

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

************** 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.
