@mitu i remember adjusting that to see what it does. now i know! looks like i had set it to 0. reset it to 100 and looks like the issues are fixed. think i was over looking this as it was one of the menu options that was opaque when selected, making it hard to read.
@h2805270 Really clever idea, looks a lot like Teletext, and clean layout too. My only reservation is that I'm not sure I'd want to spend too long looking a Teletext screen, as they're not the easiest on the eye. I was never a big user back in its heyday though, and others may well have a greater fondness and nostalgia for it.
