Text Recognition / Edit
Older versions (prior to text recognition) allowed you to type onto a pdf and edit it later without any interference. The new DC software while still allowing you to type and edit more than often enough recognizes the original text of the document making it editable and causing tons of interference with the user entered text. There should be a feature which locks text recognition and doesnt allow the editing tool to recognize the base document script which will allow for easy editing if you have to save and come back to a document and make changes.

Previous versions of Acrobat allowed me to insert text without the software editing on its own, unbidden. Now, in order to enter text, Acrobat insists on editing the file - BAD change! My pdfs involve a lot of math, and your editor totally screws up the equations (see for yourself!). So, I can't enter text without ruining my pdf. PLEASE revert to earlier versions, where editing (or not) was under my control!! Or, fix your editor, so that it works on complex math equations. Thanks, Terry Dupuis (customer for 10+ years!!)
