VirtualBox VM can also run in "headless" mode, either by running it using VBoxHeadless (command line tool) or as a windows service: http://mkrmr.wordpress.com/2011/05/06/running-a-headless-virtualbox-in-windows/[^] You can then configure win service to auto-start, or create start-up script/batch to run VBoxHeadless.

Are you writing a console application? Then Console.Out is your standard output.

Thanks, that was the problem.

When I'm signed out code formatting in preview works OK, but when I sign-in it stops working:

var x = GetX();

Does anyone else have this problem. Tried both FireFox and Chrome.

incorrect - yes, I'm not talking about sync-ing threads. My point was in that case code would not be "Testing the obvious..."

We do not see the scope of fileName. Maybe another thread can change it's value :)
