Message box telling no subtitles were found is not necesery

No one needs a dialog to tell him no subtitles were found! It is very visible that no subtitles were listed below. And the user need to click this OK button which can be very unsatisfying if you are planning to look for more subtitles in a row. Every time you have to use mouse to click OK end begin g again instead just dragging new files into Sublight.
It is actually very annoying and completely unnecessary! Please, please remove it!
