Fullscreen/Windowed Problem

[seaeye]

I have been having an issue since the second patch where by if I switch my resolution from 1920*1080 to a lower setting I end up with the game running in a sort of window that doesn't fill the whole screen.

Instead I can see parts of my desktop as the game is running. Also, this is only when the sim is running, not while I'm in the GUI.

I have read similar posts on this subject, but there has not been a proper solution posted. I haven't had this problem with 1946..

Is there something I've got to alter in the conf.ini to make it fill the whole screen at my chosen resolution?
