Updated to 3.4 this afternoon and noted could not install any widgets to my static home page that seemd to work before. Noted that adding a title to the page resolved my issue and the widget page working fine again.
Finding another post on this I went into my style for image browser and commented out the 100% width of img and noted the nav elements and title were still floating relative to 100% width. I then added a fixed width of 300px to the first element in the Image Browser section and now all displays as it should.
On a lark I just selected “Enable AJAX pagination:” and now I can navigate the gallery.
