If you go into a saved document and change something you cannot save it you have to save it as a completely separate document. i.e. I edit one line to be italicized and hit save and I get a pop up error that states, "The file may be read-only, or another user may have it open. Please save the document with a different name or in a different folder.

1) I am the only user
2) I created the .pdf document yesterday and did NOT make it read-only.

pdf documents not opening properly, with blank pages. It is worse if I try and scroll through the article soon after opening it. It will also loose text from the after a time not reading the document. This may be after the computer has been put to 'sleep' for a period (even a few minutes). It reports the error message 'Insufficient data for an image.' The new version is MUCH worse that previous versions. Please sort it out Adobe.

Steps to reproduce the issue: Open Acrobat and move window from one screen to another.
Environment (OS, other related application versions, etc.) Mac OS 10.14.1, 2018 MacBook Pro
Expected result: Should not crash
Observed result: Crashes consistently

Acrobat DC keeps crashing. I don't know if the crashes are being reported back to Adobe or not. It is Hanging/Crashing on SaveAs and during editing.

I would like to add tags to PDF files that are inside of a Windows folder and be able to filter by tags.
At the moment, the naming convention organises the PDF files in an order that is not beneficial for us.
Can we add tags to PDF files and filter inside of a Windows folder?

I can't email a PDF file directly from documents-just started recently. Have always been able to do so.

Whenever opening pdf file, Acrobar Pro DC always shows a window titled as 'content preparation progress". This takes too long and blocks file content & makes hard to read file content.
Sometimes several minutes, sometimes forever!
This needs to be improved.

Unable to "save-as," export, or e-sign a PDF document.

Error message when trying to export as another PDF file type, or as another PDF with normal "save as":

"The File may be read-only, or another user may have it open. Please save the document with a different name or in a different folder."

I am using Acrobat 9 Pro on a Mac OS Sierra 10.12.6.

DC Pro is totally unreliable, whether creating a pdf, trying to access a pdf or saving the program displays "DC Pro not responding. Happens very frequently making the program useless. Have worked with support 3 times no resolve. Occurs on both my WIN10 and WIN7 computers, never had a problem with ver 7 through 10. Pay lots for DC team but will have to look for another vendor.

There is a bug in this software that does not allow you to save the document. A blank window pops up and nothing shows, i.e. where the file could be saved. Only after several attempts does the "save as" window fully show up. What is the solution for this bug?

Acrobat just crashed due to file size, and could not be recovered, just lost everything.

if I open an existing PDF and make changes it will not save, if I create a new PDF it will not save. I have tried save, and save as neither work. and I need this to work for my job.

In versions before Acrobat Pro DC you could scroll through advanced search results with the down arrow. Now you must select and click on the entry, a HUGE time waster and annoying step backward in Acrobat's functionality.

File rename option should be there.... essential

What happened to the +/- zoom function? I need the ability to manually input the % of a zoom when comparing files; so that I am comparing "apples" to "apples" when it comes to the percentage size the the zooms. Why does it seem that every new version of Acrobat worse than the previous version?

What happened to File-Save and File-Save As? Adobe Acrobate Pro DC updated itself and they're gone.

a word look up ends up with '404 Not Found' using:

instead it should use:

Have a download button which facilitates a download to the customer's computer instead of just getting the page address downloaded

In Acrobat XI on Windows I save as the file to create another same file. But the text in the creating file has been modified.
Steps to eproduce:
1. Open the Demo File.pdf and click "Save As" in File tab.
2. Give a name and save it somewhere.
3. Reopen the new file you will easily find it is not the same as Demo File.pdf
