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.
Noticed this in my fork and was wondering what was causing this and then tried your version and the same occurs. And found out that the server where I wanted to connect to wasn't available for some reasons.
Actually this shouldn't result in an exception or is it on purpose? As line 413 shows 'throw'.
In my fork I made some additions that it will complain.
