Does the recent files list change at all between program sessions or is it more like it's stuck with the same list every time you restart the program?

The list is stored in moi.ini so if it seems like it's stuck then maybe something like security permissions are preventing MoI from writing to the moi.ini file.

You can find where moi.ini is located by going to Options > General > "Edit .ini file" button, the dialog will show the location of the file.
