Black background on expanded figures in iBooks Author - we need the white back
Hi,
It seems there's been a change and now all expanded figures in our iBooks appear on a black background. (Or somehow I've done it?)
This is a major problem as many have transparent backgrounds with black lines - they are basically invisible in parts. The figures are technical drawings and need to be accurate.
Is there any way to change this back?
