"'Start New Subject for Discussion' box does not have the editing tool bar and the '?' above it like it does in Internet Explorer 9?"
It doesn't have it in IE7 either. What's more, if you hadn't mentioned it, I wouldn't have known it was supposed to!
(2) I can post a thread in Firefox 4, but not always, but that's better than my experience with IE7. For as with that I haven't been able to post a thread at all in the new PCA format?
Of course then there's the posting to someone elses thread. After I post, I have to come out of that forum altogether, before I can post to that thread again! What is that all about?
