Thanks, you're right.  This is not a problem on the latest build.  Good to know.

Hi Brad,

From the exception details I saw that the installed Nevron assemblies are version 11.1.17.12.
Please, download our latest version 11.9.27.12 where this problem should be fixed.

Let us know if the problem persist.

Best Regards,
Nevron Support Team

I'm using Win7 and when I run the Examples (Nevron UI/Winform/Examples C#) and via the menu select a new frame (e.g. Edit>Frame>VistaRoyal) I get an exception box.  Can this be corrected?  Here's the exception it reports:

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.
