Hi Samuel, I'm glad you've got the initial problem solved!

re: file caching - that did get implemented in Moi v3, go to Options > General and push the "Edit .ini file" button, and inside there set DisableFileCaching=y . That will make MoI freshly reload the file every time a command is run rather than caching them in memory like it will do by default. More info here:
