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

Mike, if you could share your file through our support system (https://www.coffeecup.com/help/myroom/) we can take a look at it.

Wayan, you are using an unreleased version that fixes the issue with the resource select button. The scroll problem you are referring to will be addressed before release.

Thanks Bob. I did not have the original file, so I created a new file with a detailed description of the problem, some pictures and a sample of the Bootstrap component having the issue.

BTW - does anyone know how I can prevent Site Designer from using wireframe-theme.css? It seems to really overstep Bootstrap classes and cause some issues that are difficult to track down if you do not know what is going on.

I know I can override the styles in the css (or edit the original), but I would also like to prevent site designer from adding all of the extra classes that I don't use (like container-grid, link-text, text-element, etc.). It is unfortunate to have to go back and remove all of those classes after exporting. It seems like a project setting to include wireframe-theme.css and the accompanying classes would be a nice solution.

I have had other issues besides the one I mentioned in my previous post - but just figured I would try to exorcise wireframe-theme.css each time I export.
