If Map Monkey runs by itself you might find that some or all of your DLL’s for Map Monkey / Destinator have not been registered or not in the working directory when Frodo Player is running, you should get an error message.
Have you tried reinstalling Map Monkey?
What exactly happens in Frodo Player? Error Message or any sign of MM starting?
You also mention “things run funny” what exactly isn’t working properly?
It’s hard to suggest anything else. You need to be more descriptive of your problem(s).
