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

Can you give any more details on this?  What had you been doing before the 
crash?

I was training a long run on image patches.  I have VS installed now, so I'll 
be able to give a post-mortem the next time it crashes (if it crashes).  I'll 
withdraw this issue until I see something like it again.

I know there is a race condition between the GUI and the trainer that needs to 
be fixed, but I wouldn't expect the chart to break in this fashion.  I'll dig 
in and see if there's anything obvious that sticks out.

Alright, I finally had this happen.  I think what's going on is that messages 
from the UI to get weights/visible/hidden/reconstruction error are being 
handled improperly if they happen to get sent after a 'Stop' message is sent.  
So the RBMTrainer gets torn down, but the request messages go in and make 
requests on a now invalid trainer.  Should be an easy fix.
