I use Acrobat and pdfs every day to save, print and share client files. With this latest "upgrade" of Acrobat DC, it usually takes at least 3 or 4 times opening a document to be able to use it. I open a document and all I get is the spinning circle. I can wait till the cows come home, but it won't do anything. If I click on the document, it says Acrobat is not responding. If I click on it again, it grays out the entire page and I have to close the program. This will happen time after time to the same document. Then on the 3rd or 4th try, I willl be able to click on it and have it act normally. This is a real pain in the neck; I don't have time to open and wait for a non-responsive program never mind having to do it over and over every time I open a new document. It never did this before this last new version.
