I use desktop. The slide show for the comic section where "This Week's Comics" has stopped working.
But the major issue is with the editing. When I click on something or paste, the cursor automatically gets redirected to another place, typically before another word. I'm editing in pure source mode.
Sometimes the source editing creates improper spaces when you add a field like say "Writer1_1 = Scott Snyder". This prevents the name of the writer from showing up in reading mode. Unless you completely remove the spaces between the = sign and "Writer1_1", then you can respace again. Most of the times I avoid this, but it's not always possible to be aware,
Also, in the visual+source editing mode, you can't see the infobox. Which is why I switched to pure source mode.
