Adobe Acrobat X 10.1.13, Win 7 64bit,
The Find function (Ctrl+F), mis-finds the desired simple text.
This is not a scanned document. When I search for some word that DOES exist in the document, Acrobat will highlight text that does not match at all and which does NOT contain the word. If I select the actual word, copy and past the text, I get the selected text accurately, but when I paste the same selected text into the Find box to search for it, Acrobat still mis-finds.
HOWEVER, I can open the very same .PDF file in Acrobat Reader X and do not have the same problem - Find works correctly in Reader with the same .PDF.
What is going on?! Both Acrobat standard, and Reader report that they are up to date. Please help.
