We produce a number of newsletters each day using Indesign. The newsletters consist of a number of A4 pages with text frames and advertisements, which are usually supplied to us as PDF objects.
Yesterday we encountered a major problem when exporting to PDF, with some objects on the first page of the resulting document moving downwards about 5cm.
The issue happens when we export to PDF or JPEG, and if we create a new document and move the items to a new page the problem continues.
I've tried removing the objects one by one to see if there's a problem with one of them but have not been able to discern any pattern.
Are the master page objects? I think I've seen reports of that and it can be worked around by overriding them to the document page, and possibly by groupeing with an object that is not moving. If they are already on the document page, try grouping.
