It’s a sporadic problem and is very recent–last couple of days.
I can edit just fine, post on threads, and can start a new thread in IE without problems. But very occasionally, the New Thread button doesn’t appear on my screen after I login. It’s obviously a Firefox 23.0.1 problem with XP, SP3 and the Chronicle software.
Oh, I cannot download my PMs in Firefox. Have to use IE for that.
