I think is more a problem with FD.
CdR has added a switch/command to his sdk that allows you to go to a RR skin instead of a Destinator menu when you press on the map.
so normally if I wanted to open fd in another menu I would have a command like
"LOAD;gps-full.skin;FreeDrive;c:\program files\FreeDrive\FreeDrive.exe;FreeDrive",""
which loads the next skin (gsp-full.skin) and loads FD which then goes into the nice little 'A' box.
but as RR is not controlling the loading of the skin and hence the loading of the app I can't put the above command in.
these are the lines I have put in the 'called' RR skin FDMENU.skin
