Editor is being way slow without much stuff in the Prezi.

The Prezi editor is lagging and being real crap. The presentation side is just fine and dandy. I am struggling to move text and images, move along the canvas/prezi/screen and connect transitions within grouped items and ungrouped items. Is this a result of the update Prezi recently went through? As the one I am working on does not have videos, large images, nor does it zoom in and out that much. It is just not working as well as it has in the past. It's safe to say, I may be a little grumpy cat about this.
