Unable to stop Acrobat DC Reader from opening Tools pane on left
I just installed a new version of Acrobat DC Reader (64 bit). I'm using Windows 10 on a desktop computer. When I open Menu > Documents and check the box "Remember current state of Tools Pane", I still get the left-hand "All Tools" menu when I open any document, even though I've closed that menu when viewing documents previously. (There is no "Okay" button to save "Remember current state of Tools Pane," but it does remain checked.) The "All Tools" menu takes up a lot of screen space, so I have to close it manually for every PDF I open. In my version of Acrobat DC, the Edit menu does not have a "Preferences" option, so I have to use the main menu to find "Remember the current state of Tools Pane". What can I do to stop that "All Tools" left-side menu from opening, every time I open a document? Thanks.
