Weird Runtime Error with C# application

Recommended Posts

When ever my brother runs this app, and I click on a combo box, i get this JIT error dialog. Anyone know why?
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.

As nickwinters said.

By that exception it's probably something you've done in Krygier_Web_Surfer.Form1.cbHistory_Click(Object sender, EventArgs e)
