Sorry, but I am not sure how to get to the original post. What I see when opening up a post, if there are a lot of replies, is nothing but the replies ... can't locate "original". Please help me. Thanks!

Don't know how you open the thread but this works for me.
IF, I want to read the whole thing, I right click on the heading, open it in a new window and then everything shows up.
IF, I only want to see what has been posted since my last view of the thread, I right click on the word NEW in the heading, open it in a new window and proceed from where I last read in the post...... I still think you can go up to the top even in this situation.
If there are little #'s on the lower left hand side of the panel, click one of those and it will back you up into the previous messages........
NO little #'s, you should be able to scroll up and get the original message. What I'm talking about looks like this [1,2,3,,,,,6], depending on how many posts there are..
Hope that answers your question.......
