Before when I would save text overlay, or comments on a pdf it would simply save. Now when I click save it acts as though I have clicked save as and will not overwrite the original file. I can save it as a different name and it will show the changes in the new file. I work with many pdf files and this problem has drastically affected my work productivity. It acts as thought I don't have permission to alter my files or as if the file is opened by another program (which it is not). Please help!
