I noticed today that I if I paste a piece of text, the cursor jumps back to the beginning of the message. Just one of many problems with this thing.
If I browse these developer forums I see examples where the fonts changed oddly, or people had trouble pasting example code, so I can't be the only one that has problems with this text editor.
I know that creating an html-based rich text editor is a pain in the a**. Maybe you can make something like stackoverflow where we can write plain markup text.
