This has been happening to me for the last week. To reproduce in Chrome, insert a logo or something like that (graphic), add in a text box, perform a couple of editing tasks on a landing page. After a couple of tasks being done, then try to go in and add in another graphic and it will stick to your cursor. I have had to ctrl-alt-delete and shut the entire window down once my curson gets stuck and it is a pain. I literally have to close the landing page I am working on after two or three edits or I have the sticky widget issue. Not very productive. Happens in Chrome, IE and Firefox.
