[Mono-dev] VisualwebGUI 6.0.4, Framework 2.0 working with Linux + Mono.

[Alejandro Serrano]

As far as I can see, the method just jumps a lot before doing something
useful, and then it just loads an static field. I can't find a place
where things can go wrong, maybe some static constructor is called
before getting the value of the static field.

I hope it helps
