JIT debugger question

Hello,

I'm developing a Windows application with VB.NET in VS2010. When I run a particular test scenario in the IDE it works fine. No exceptions thrown. When I run the same scenario with the installed executable, it throws an exception as shown below. Why might it work in VS2010 but throw an exception outside of it.

Thanks in advance.

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.
