Hi Jeff, (sorry for the cross post)
Can you please post here the data structure of the files wparam.ids and lparam.ids.
I have already tried
Winamp_Previous_track_button 40044
Winamp_Next_track_button 40048
Winamp_Play_button 40045
Winamp_Pause_Unpause_button 40046
Winamp_Stop_button 40047
Winamp_Fadeout_and_stop 40147
Winamp_Stop_after_current_track 40157Â
but this is not the solution.
with best regards
Leo
