<p>I'm not that up on VB.NET, the application I'm working on was not written by myself.<br>
It works fine through the IDE but once I run it from the exe it gives me the above error.</p>

<p>Any clues?</p>

<p>This is really hacking me off!</p>

The only user defined break point that I can think of is
```
```
Debugger.Break()
```
```
So, I would suspect that the .exe is compiled in debug mode.  I would recommend
Reflector
to look at the code and find out for sure whether or not there is a Debugger.Break() somewhere in there.
