If I wait to see the first letter before typing the second one, or if I press F2 and wait a bit, it doesn't happen. But I'm not doing that when I type, and I probably shouldn't have to do it.
 

This problem doesn't happen in *normal* editing (NON-WYSIWYG), which is good. NON-WYSIWYG works well... don't break it!!! 

 

(The reason why I'm looking at WYSIWYG -- even if it feels a bit slower -- is because of the popup editor and the weird UNICODE references it leaves in my text. I need to use it for now.)
