Before going into my problems, awesome work to everyone involved in producing such a high quality mod and I'm currently having a ball playing it. 
I currrently have two problems;
The first is the fact I can't play the game in Window Mode for some reason. I've searched the SS forum with things such as window mode but I'm barely getting any info, and many of them are no help to my problem. I read you need to edit the default file in the SS mod folder. This is how mine is currently:
I read that the windowed, bordeless_window and autobordelessmode all had to be true, however before editing the file they were all already selected as true. I thought I may have read the information wrong so I tried putting them to false but to no avail. I've also tried to edit the main medieval.preference file in the main MWII folder to windowed = 1 (which is what I did on the vanilla MWII to get windowed) but that didn't help either. Is there something I've missed or am doing wrong?
Secondly this is more of a bug but may as-well put this in here (should be put in the sub-mod section actually...) but the Heir Ancillary sub-mod in-which you can choose your next faction heir doesn't seem to work. In my England campaign I click on the Heirs Crown on my current Heir and move/drag it to who-ever I want to be my future heir. Then I kill either my Heir or King off and instead of the Prince/Heir going to who has the attribute of the Heirs Crown it instead goes to a random in the family tree.
Thanks for the help.
