I'm looking at the MM black border problem.. could you try open MM config then set it to restore size & position on startup to a custom position of 0 and 0 and size of 800 by 600 ? I want to have the input of some other people to see...
Regarding closing MM from it's menu -- it will work IF and ONLY IF you enable the TCP/IP interface on its settings -- open Settings.ini (from Map Monkeys folder) then edit where it says [Plugins] to look exactly like below:
//Allow custom apps to interact with the frontend?
The above also allows for RR to pull up data from MM.
