--- Comment #7 from faalagorn@gmail.com --- Thanks again for reply! I'll wait so hopefully staging will catch up then and continue using the patch in the meantime.
I also want to say that my bug when the game loses focus still occur still happens, but that might as well be game's issue. It's still good enough with the updated patch, so if it still solves winamp (and potentially other) issues it's fine as it didn't made any regression for me :)
