Well done for providing a Welsh (Cymraeg) localisation for Limewire! However the flag that's shown on the language selector dropdown menu for "Cymraeg" is not the Welsh flag - it's the flag of the United Kingdom (which in fact for various historical reasons does not contain any trace of the Welsh flag). This is a bit like supplying a "California" localisation but showing the US flag next to it.

The flag of Wales may be seen at this link: http://en.wikipedia.org/wiki/Image:Flag_of_Wales.svg
