I had "enable scrolling" selected in the VIEW>PAGE DISPLAY MENU when without warning it would revert to the single page view. I went into EDIT>PREFERENCES>ACCESSIBILITY and set "always use single page continuous". The same thing keeps happening. I am creating bookmarks in a long technical document, so the same actions are being continuously repeated. As there is no visual indication whether single page or scrolling is selected, it is difficult to determine if any specific action is triggering the change.
Can anyone offer advice on this - I have re-installed the program twice with no difference.
