Is anybody else having trouble with the Canvas editor freezing up for Pages that contain an iframe?
I see this, but clicking on the HTML Editor button does not give me the HTML view I need to edit the page, and clicking on the Cancel button does not work. I have to close the tab and exit. From what I can tell, this seems to be happening ONLY on those pages where I am iframing a Canvas File. It does not seem to be happening when I am iframing something that is not a Canvas File.
Anyway, I'm posting this for future reference just in case anybody else is having troubles. I was able to fix the problem by moving the File into my own webspace and iframing that. Then the Editor behaved once again. :-)
