By the way, notice how the screen jumps up one paragraph after the backspace. It might look as if the cursor moved, but actuallly it is the edit area. Another extremely irritating thing, but I somehow got used to it after moths (years?). Combo with bonus italics is quite too much to bear though.
Okay, so instead of “spamming” I’d like to mention another wordpress bug: the text editor often moves random words to the next line without a reason, therefore leaving blank space at the end of the previous one.
