Saved them (many times - I've tried this many times), and they save ok. File not read only. If I put a number 3 (or even 4) in the relevant line then the slider (in game) reverts always to the position in the photo. If I slide it in the game it stays there, then I close the box and when I re-open it it's reverted to the position in the photo. Doesn't really matter, as the graphics are fine as they are, but I was just wondering why it doesn't slide all the way along?
