Hi, I talk about the editing problem in this post: Libre Office Editing Problem
It includes screen shots. This is happening both before saving as a file type (when creating the file) and after it has been saved as an .odt file. I have been using the right click menu to edit, perhaps using the toolbar buttons produces a different result? Even selecting an image to begin resizing it starts the problem.
As I mentioned in my last post, unmaximizing then re-maximizing the window clears the problem and I can continue with the document.
