The save command is grayed out when I open a .pdf document in the Acrobat Adobe Reader viewer. I used to "save as" once opened, but now this command is not working properly, I think it happened after an operating system update (windows 10), so I thought this was related to it, but I can say... The keyboard short Shift-CTRL-S is not working either... but it used to work and it works with other files like .odt or .doc The point is: why could I do save and save as when already have the pdf document opened (pdf viewer) before and now this button is grayed out and cannot do save or save as anymore? I'm not doing nothing wrong using Acrobat Adobe Reader DC, because I do exactly the same of what I used to, and it always worked, so now it's something different... Please help!! Thanks in advance!!
