What steps will reproduce the problem?

void main() {
  var a = 10;
  var b = a + 5; <-- breakpoint set
  print('$a, $b');
}

What is the expected output? What do you see instead?
expected: debugger should stop at breakpoint
we see: program runs until end

What version of the product are you using? On what operating system?
Dart SDK / Editor version 9474 - Windows 7 Professional 64 bit

Please provide any additional information below.
Debugging web applications in Windows 7 DOES work!

Cheers,
Ivo Balbaert

The implementation of command-line debugging hasn't been ported to Windows yet. We'll adjust the UI to make that a bit more clear. When we have an eta or a better idea of when we'll have command-line debugging for windows, we'll update this bug.
