Hey mate... I found what I think are 2 bugs... One in spanish translation ---> "Check Now" appears in english... what would be "Chequear ahora" (In exact translation) or "Buscar actualizaciones ahora"/"Buscar ahora" (In a better sound translation)...
And the second one... I that I clicked "Check Now" and then it appers a word in bold saying the is searching for it... but It doesn't disappear... keeps searching until I close the config box... never found nothing or never say there is not a new version... I have the most reacently WLM and MP!L release... (I though that can be a problem with my AVG Internet security firewall but now I don't think so...)
