BackgroundWorker SecurityException: "Request Failed"

Hi,

I've copied the sample code from the .net2 framework docs for the
BackgroundWorker class, but I'm having problems running it! If I compile
it and launch the exe, all works fine. If I launch it from Visual C#
Express (Beta1) by pressing Ctrl+Shift+B, or if I access it via the
webserver ("no-touch deployment"), I get the following exception.

I understand that "no-touch" (not clickonce, I'm just running the .exe
directly) has security restrictions, such as only being able to consume
web services on the launching domain, and no FS access, but something as
simple as Threading I thought would've been covered! :(

Here's the exception; if I can provide any more info that might help,
just ask. Thanks :)

Click to expand...

I actually meant Ctrl + F5 for launching from C# Express. The app runs,
but gives the same exception as when launched through IIS :(
