Default [Q] "Set S-view window colour" - disable message?

I've also posted this in the Alliance ROM forum, but I'm not sure if it's a ROM-specific bug, so I'll try here too if that's OK.

Small but irritating problem - I have the Samsung flip cover (not the s-view cover), and I suddenly have got the "set s-view window colour" screen when I open it.

It flashes up and disappears quickly, but it's a PITA, and I can't find a way of disabling it.

My boy used the phone yesterday and I think he managed some unusual button press combination.

As always thanks for any advice.
