Don't recall if this has been reported, but I can only get racks to play with Z3 by manualy loading them with the explorer button, which is okay cause I have to do that to manualy copy them to the Ramdisc drive. Anytime I click on the actual library button I get an "unhandled Exception" error. When I then hit "continue" nothing happens.
Also, assuming Z4 will copy files to the Ramdisc in a way that mimicks manually copying them, is there anyway this can be done for saved playlists, so that when a playlist is selected the files get properly copied? Sure hope so.
