is there any way to intercept network traffic of a given program

manipulate and then continue sending the data to the "real" destination?

The programs "freecap" and "sockscap" do something like that, but sadly only support socks proxies

If anything like that exists in the .NET Framework I'd love to get a pointer to related APIs.

Ok, so I'm not hallucinating, something really strange is going on here.

I'm inclined to think it's a bug, but I don't really know.

Obviously there are ways around this, but I shouldn't have to do them. I'm not doing anything special!

[Added] I typically don't call dispose on controls, except for forms/dialogs, since
my controls tend to always be part of some Form, and I trust .NET to dispose properly

you shouldn't call Dispose on controls and GUIs

If you want to remove the control from the parent collection, do that. Don't invent some convoluted system of destruction just to remove a control from the parent collection.

int a=12;
string s=a.ToString();
