I dont know if you all faced this, bu the in_mpc 0.92m shows the Artist and Title in Winamp's title windows and the taskbar as %1 - % 2 instead of the actual values.

This problem was not there in the earlier versions.

I am running Winamp 2.80, in_mpc 0.92m (Downloaded from Frank Klem's site) and Win 2K.

Title formatting syntax was changed in 0.92l, but the version on Frank's site was buggy and it probably didn't work. You can change the formatting to %A - %T in config.
