if you are downloading the 0.845 version from the download page (should be the same as on the forum - I think) and only changing the prefix, then it should work. That is what I just did and it works fine with the prefix monkey.
Skylive:
Please note that I changed the default commands from play and pause, to "music play" and "music pause" because the one word commands get fired off accidentally too often. Of course you can change this back but for new users who don't use prefix mode, I wanted to avoid that problem.
So "Monkey Play" would not work, but would show up because it is waiting for you to finish the sentence. eg "Monkey Play Artist Beck" or "Monkey Play Next".
Kalle:
The fact that it is showing up in your command history but not doing anything is really REALLY weird. I can't explain it. Unless it is having trouble connecting to MediaMonkey, but this has nothing to do with prefix mode.
Wanilton says he tested 0.845MM with the prefix "monkey" and it worked fine...
Please test some other prefixes, and some other commands.
If you can't get it to work, tell me exactly what you are starting with, AND exactly what you are modifying in options or the command tree.
Or send me a zip of your complete folder.
Or get this version:
