Possible to permanently disable the "This appears to be a long document" popup header message?
Hi
Is it possible to permanently stop the "This appears to be a long document ... save time by reading a summary" popup header bar from appearing when opening a PDF in Acrobat Pro?

It's becoming a nuisance when I am working on a document which requires frequent exporting, to have to hide this message every time, as it usually appears a few seconds after opening the PDF, by which time I am already in the middle of checking/proofing and it breaks my rhythm.
Thanks
