Guild of Writers

Been going through the available tutorials on using the plugin. Just got to the ones on adding sound. I can't seem to be able to select a sound file. When I press the button that says none under Sound Name nothing happens. I assume a dialog box is supposed to come up. Is there something else I need to do, does anyone else get this? I'm using the 2010 plugin.

I think it's a bug with the plugin. Normally a Windowsbrowser should open to select the file.
