Since TR put up their new discussion center software (which I hate and believe has driven off contributors), I’ve been bothered by problems making edits to my posts. They disappear, sometimes.
I’ve found out why. Try to edit an existing post, and add a paragraph on the end, and save it. Then say, “Oops, there’s a misspelling in paragraph one; I’ll fix that,” and re-edit, and save. Then say, “Gawtdamn! Wha happen to paragraph two?!” Because it’s gone now. Your misspelling is corrected, but the first edit has disappeared. Edit again, add the paragraph, save, and surprise! The spelling correction diappears now.
The edit buffer does not refresh until you refresh the whole window. If you edit over and over, without refreshing the window, you will keep going back to the original text every time.
