also, good point on the radio thing. i should try out the same feature in other skins to see if its a skin issue or rr issue (for the basics such as navi, radio, etc). i.e. i found a post stating that adding EmbedAppList=iGuidance may solve the iguidance closing issue so i'm going to give it a shot (just posting here incase someone reads it).
as for the file browser, i played around with it more and copy-paste does indeed work, however i dont think the list is updated til it is reloaded (i checked this when i used the delete button, and the item was still on the list). my E: and F: drives both contain files but nothing will load when they are clicked. if you'd like i can post a debug file.
i also have played around with the playlists and created a separate folder called (--Playlists--) like you suggested, but this history feature is weird. I suppose it works ok for going backwards, but then if you try to go forwards afterwards it gets screwed up. At one point, all 5 playlists got written with the same track list, which was basically just one music album, even though I had added 5 into the original playlist. If you could post basic instructions on how to use the playlist feature, including what the rename, delete, and save buttons actually do, that would be helpful, because as stupid as it sounds i can't figure out how to make and save a playlist, or save an already playing one and name it what i want.
