Recent development of Adobe Acrobat is awful, saving works only 1 time out of 7. Can not oven covert, the button is here but does not do anything, just a frozen screen. Totally unpredictable, I have chosen the directory, and suddenly it just does not work, and I need to repeat. It seems like constant glitch. I had used the previous version, always worked perfectly, this one is like unfinished faulty one.
