I remember editing some posts in the JottiQ topic causing tons of question marks to appear at places with multiple spaces. Let's see if I can reproduce it.
Blah Blah Blah.
Blah Blahblah blah!
Did a ton of edits on this post just now and I can't seem to reproduce it. But it was a bug that happened after you first fixed stuff, so it might well be you need to get around to fixing before I can trigger it again.
