2 points about the 'preview' button... If you're going to use it... First click and drag your mouse over your post to highlight it, then right click and save it. Another malfunction of the preview, at least on my browser, is that when you start a thread, if you preview and then post it, it will not display the 'caption' that you select for the link that you embed in the post. It will just show the link itself, spelled out. To insure that your caption is recorded, use your back button and click the 'post reply' button that you originally bypassed, to use the 'preview post' button.
