Since this game rewrites its medieval.preferences.cfg everytime the game starts, editing it is impossible.
You simply create your own copy of the .cfg and use a .bat file to call it rather than the original

The last mod I used the trace switch the syslog was tremendous.
Thats why you open in Notepad and use "find"...

I see from factionheir's note that he spotted something anyway.

Sorry I was just trying to be helpful having spent a few hours yesterday and this morning resolving a problem about .SD files.
