I'm experiencing a strange Org bug in the latest few versions. If I have a #+CAPTION line, I can type my figure caption as I would expect. But as soon as I pass the 70th column, the spacebar triggers an error. I can type letters after the 70th column, but not a space. When I press the spacebar on the 70th or higher column, the mini-buffer says:
Buffer ` *temp*-624801' still has clients; kill it? (y or n) I see no effect if I press y or n, and can continue to type letters, but any additional spaces repeats the error. If I change the line from #+CAPTION to anything else (##+CAPTION #+CAPTIONN etc.) the bug does not exhibit. -k.
