Well my latest isn't exactly the same but I have rub into an issue similar. Only 1 page into the project and not big or heavy with much. I noticing the element tree thingy that it wasn't displaying everything in the body I had inserted a container with text and paragraph and image all the element tree displayed was the container and the text no matter what I tried just couldn't get to the bottom. Then I noticed that the new fangled thing on the bottom of the canvas that normally displays the elements was blank nothing nada zip was being displayed I restarted without saving to see if I had dine something to cause it but on opening still nothing and still element tree not showing full list.
I am seriously thinking of uninstalling and going back to 3.0 them more I use 3.5 the more I am finding that makes it hard work to even rate a simple page or two
