Rita, I run into this all the time. When it seems like the post has not loaded dont believe it. It loaded. You can refresh the thread in another window and you will see your post there. Just go close the posting window that is still 'thinking'. Works every time.
I will try that again. Thx. I have done that and found it did not post lost my post entirely. But, I am on my cell phone working in miniature and not all that proficient.
