After a lot of mucking about with different formats, I decided to go back to good ol' OGG format for my ripped CDs, so after quite a while of not using it I re-installed OggPlay v1.7 and the provided 240x320 skin. Now my web browser is using the same rather minimalist font that OggPlay uses.
This is ringing very loud bells with me. I'm sure it's been discussed before but I can't find anything searching on this forum or google. Can anybody point me in the right direction?
