Strange, MP prompts me to upgrade to before it allows installation. MP will not allow installation on anything below 4.9. Everything seems to be working with MP .65 and iTunes 4.9, except for Foobar2000 passthrough with Kernel Streaming. I'm running XP SP1, and I changed the Quicktime setting as instructed, so it works with waveout selected in Foobar. However, Kernel Streaming is supposed to be the setting for highest quality sound out of Foobar, so I wonder if the benefit of using Foobar through iTunes has reached it's full potential yet. Also, clicking on "Foobar Settings" doesn't do a thing. Otherwise, works great with 4.9~! UPDATE: MP seems to not allow maximizing the iTunes window to fullscreen. Double clicking on the titlebar does nothing, and clicking on the green + button takes it to the mini player. Anyone know how to change this back? I thought there was an option in iTunes prefs, but now I don't see it. Also, it may be because i went from 4.7 to 4.9...anyone know?
