I keep getting this message when creating a new document. You can see my settings below it. 1 column, 0 margins. The only way to get around it is create a different size document and then resize. Very inconvenient not to be able to use the presets. Any clues?
Functions for me with CS4, CS5 & CS5.5.
What are the exact steps that cause this issue? It looks like you have a document open. Does it happen when you try to define the preset with no other documents open?
Have you tried resetting your InDesign preferences?
This happens to us when you have another document open which is huge, not sure why this happens and never chased it up to find out.
Try creating the same page again with no document open.
