Hi All,
I have been using org-mode and emacs for lectures in an engineering course. I often have equations, and then source blocks that implement them. I can display the latex fragments, but when I try to run the source blocks, I have to type C-c C-c twice, because the first one removes the overlays, and the second one runs the block. that is pretty inconvenient, because then I have to put the overlays back on.
