I'm also not 100% sure whether it's a WordPress problem or whether it might be my browser (although I've tried it in this form and it doesn't happen). Anyway, here it is:

As I type I make mistakes and have to go back and delete. Generally, I've got into the habit, rather than using backspace to tap back through the letters, of pressing Ctrl + Shift + Left Cursor to highlight the word I've just typed, then just typing the word again.

The problem is that when I'm typing in a New Post form, and I do this, when I start retyping the word the preceding space disappears, so my new word runs straight on from the previous one. If I remember, I'll start the new word with a space, but I wonder if there's a setting somewhere that I can tweak that'll preserve the preceding space?

(Actually, while I think, if someone's in the mood to help out with trivial questions like that... As you can see I'm one of those old-fashioned people who uses double spaces between sentences. I know this is hopelessly outmoded, and that HTML doesn't support it, but I just think it makes things easier to read. The trouble is that while WordPress respects my double spaces, if the end of a sentence coincides with the end of a line, I end up with my next line indented by one character. The second space gets added to the start of the next line; but word processors like Word manage to compensate for this and preserve the left-justification. Aside from the obvious "wake up and join the modern world", does anyone have any ideas on this, too?)

Any replies appreciated, thank you.
