How do I turn this off - "transparency mode"
Hi,
I turn something on. And I don't have any idea, w. In "preview mode" the background becomes gray. It's good to see, what has transparency, in somehow. It only happens in one specific spread of the document. When exporting the in pdf or png, these pages, comes in white. The document is not corrupted, I have inserted new pages, after the "feature" and paste something old and new, and no dada was missing.
