I often have multiple windows of Okular open with different documents. Some of these documents are slides that I browse with continuous view off, but some are papers/longer documents that I browse with continuous view on. However if I turn on continuous view in one window, turn it off in a second window and come back to the first strange things happen. The view blocks completely until I toogle continous view 2 more times, the view is displayed continuously although the menu setting says otherwise, and so on. It is really annoying and has been like this for some years now. I hoped that the recent changes of saving continous view mode for every distinct file would solve the problem but it's even worse now. I only open one more file, the continuous view flag gets loaded and locks up the other windows. The problem seems to be that this boolean is somehow global although it really should be a per-window thing. STEPS TO REPRODUCE 1. Open one document, turn on continuous view 2. Open a different document in a second window, there turn off continous view 3. The first window should act strange. If the problem doesn't show right away try toggling the setting a few times while switching windows, it should appear pretty soon. OBSERVED RESULT Changing continous view in one document affects all other windows in strange ways. EXPECTED RESULT Continuous view should be a flag that is distinct for each open window.

I just found out that this problem has been reported before and there was an attempt to fix this in bug 388952. I'm not sure if that changes made it already into Okular 1.10.0, but if these changes are in fact in Okular 1.10.0 the fix did not work. Bug 341318 is related to this, there saving continuous view for every document is described.
One more comment, sorry for the incremental information: In bug 388952 it was claimed that these changes made it into 1.7.3 so it seems that the problem is not fixed yet.
Others state that different settings for Continuous mode work in their Okular. How do the other view modes work for you (Single Page, Facing Pages, ...)? > However if I turn on continuous view in one window, turn it off in a second > window and come back to the first strange things happen.

I never noticed such behaviour. I had similar bugs while moving the Continuous option to the View Mode submenu, but I fixed them as far as I could test. Can you make a screencast, so the problem is clear?
Created attachment 129101 [details] Screencast: Okular continous view bug
I created a screencast of the page lockup and attached it to this issue.
Your screencast makes it clear, thanks. I would describe it as: When I toggle Continuous in another window, the PageView in the first window freezes. When I continue toggling in the other window, PageView eventually unfreezes. Did you observe other kinds of “The first window should act strange”? Right now I don’t have an idea what could cause this. There are more changes planned to scrolling, so I will not investigate yet. (Besides having little time.)
