Can't track opened file under Windows

[olostan]

Using Windows, I started program with '--debug', opened editor on that file, tried to enable extension, clicking on panel, but got:

Telling editor we're connected to the debugger           
[1] Calling _debugger.getScripts(Object), replying to 0  
[1] Got back undefined,                                  
[1] Notifying callback 0                                 

May be that is problem with different URL formatting of local files? I got as parameter of getScrrpts kind of { filter: 'C:\\Test\\xxx\\test.js' }, but using other node debugging tools I files without paths....
