Sorry for the delay. It's because I couldn't post a reply on my cellphone [/irony].
Anyways, simple blue didn't work for me either. I did press a bunch of buttons, though. I can press all the formatting buttons on the top of the reply box. I can insert smilies and links. Reply with quote auto-populates the text box with the quote. However, I cannot click in the text field and select or type any characters. It is probably good for everyone that I cannot instantly reply with my stream of consciousness on every thread. Having to wait until I get home and type stuff allows laziness to filter my natural excesses.
