Then try my script, it works in WB. I use WBRun
to open AmiModRadio.
Edit: The HIDE option of Hip will open it invisible, and the QUIT one will close any existing Hip playing, but also will "erase" the Hip prefs for what I've seen:
I use some Hip prefs that load a module that I've got when you start it, but if you open AmiModRadio with my script and the QUIT option it won't, it will only open the one your program finds. It doesn't overwrite the Hip prefs; next time you boot, if you play Hip (my case) it will load and play my module again.
