Unhandled Exception
Using VarAC 13.01 on Windows 11 25H2. I open VarAC, double click on a broadcast, highlight the broadcast, and then right-click copy. I get this every time:
Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.
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.


So I checked the PC, and Clipboard History was already off. No other anything that would use the clipboard is in use. I tried the test again and it happened once and then I cannot replicate it. I tried copy/paste with notepad and browsers an errors. So that makes this intermittent. Difficult to trace.
