I am an experience user from 4 to now 9 standard. At work when extracting pages from a block scan I keep getting "one or more pages are in use and could not be deleted" it does not extract the pages but deletes some and leave some in the master document. This happens on a regular basis and is so frustrating when trying to split a block document into individual ones. This is on adobe 9 professional... Process is 3500 pages document, open up the page tab to see the pages. Highlight the first and last page of the document you want to extract. Right click and select extract, tick the box delete after extracting. Some times it works and a lot of the time I get the error above. I have google’d this error and there seems to be no feedback to cover the reason as to why it creates this error and what does it mean?
I use this feature once a month to extract / delete some 200 pages from an 800 page file. I found the release notes for 10.1.4 stated that this issue was fixed. I updated my Acrobat to the 10.1.4 release and i was still having the problem. I finally fixed it by disabling the Win XP compatability feature that i had enabled in the properties of the Acrobat executable. I had enabled this feature a couple of months ago as a fix to this specific problem, now it's not necessary.
Environ: Win 7 32-bit and Acrobat X, 10.1.4.
