After what seems to be a random amount of time, the 1.7.4 Xibo client will crash with an unhandled excption. The display continues to update some of the items for a short time when the error message is up. If I close the exception, the whole program will close as expected.
The exception is listed below.
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.
This has been happening since I upgraded to version 1.7.4. I am not sure how to proceed in diagnosing this crash. it seems to be happening about an hour or two after restarting the client PC.
