Anybody have any idea what might cause this in IE8? The background is meant to be a solid blue, but as you can see it's not. This is not on my machine and I've been unable to reproduce it, but one of my clients is getting it:
More details: The background is using a png (which it doesn't strictly need to as it's a solid colour, but it's a legacy app so you know how that goes)
Also he says he is getting it on 2 machines in IE8. But all works fine on his end with chrome and firefox. I also have tried it in IE8, firefox, safari and chrome and they all work fine.
