I am trying to edit [[Queensland Cultural Centre]] to merge the existing article with other material. The problem seems to be that when I move a heading and its content into another section and click Published Changes, the VE hangs. There is then nothing that can be done except to click on Article and abort the edit. The problem has happened many times now but I cannot provide any diffs, because I can never save the result.
But take [https://en.wikipedia.org/w/index.php?title=Queensland_Cultural_Centre&oldid=826472167 this version] and try to cut-and-paste the section "Queensland Gallery of Modern Art", the photo captioned "Queensland Gallery of Modern Art main entrance", and the paragraph commencing "The Queensland Gallery of Modern Art, which operates in association with the Queensland Art Gallery ..." from its present location to above the heading "The Queensland Gallery of Modern Art, which operates in association with the Queensland Art Gallery" a few lines earlier. I select the desired heading and para (which picks up the photo as well), cut it, and then move up to the desired location and paste it. Immediately something odd occurs . There is an extra line saying
Heritage listingQueensland C
and the heading that you didn't touch is messed up.
At this point, Publish Changes is blue, but if you click it, everything hangs! I have done a series of screen shots to illustrate each step of the process.
