Opus 9: folder tree won't receive color

thanks for the faq page! it did help, but it didn't solve the folder tree problem. what i decided to do was import only the colors from one of the default themes, then just go back and overwrite them with my own. it worked!

here's a sample filename:
B:\挽回\foo.mp3

if i highlight that in viewer to play, the play button is greyed out and disabled. if the filename is longer than 8 char, it truncates it to a ~1 filename like BLAHBL~1.mp3 or something like that.

also, i have a question about the flat mode. the other day, i made a button that would open the parent folder of a file highlighted in flat mode into a dual window. is there any command that i could add that would make opus automatically highlight the file in the second pane that was highlighted in the first pane?

i saw here that you can have windows media player play a file from within the viewer. is there anyway that i could use The KMPlayer instead? i think it's probably best video player i've ever used (well, of mpc, vlc, wmp, winamp).

thanks for the prompt replies!
