Question about Outlook Express

Replys to my emails - Outlook does not reflect the entire reply.  How do I see entire reply?

We used to have a "Forward" button to send an email to someone else. That option is no longer available so how can I share an email without doing a bunch of other stuff to get it to another?

I wrote a question earlier a few minutes ago, when I went to access my e-mail today and, for the first time, found that using the mouse to select a message (to read it on the reading pain at the bottom) didn't work.  At first, at least I was able to go to a different message by using the down and up arrow keys, but within a few minutes, even this didn't work - when I tried to use the arrow key, only the message itself went "up and down".  Normally, I would just click on another message and would "get out" of the message, and then would be able to use the up and down keys (or the mouse, by point and click) -- HOWEVER, the mouse no longer works to be able to select a message, so I can't get onto any other message, unless I go into the mode of viewing the messages one at a time.  I prefer to use the  bottom reading pane for most items (it's faster).  What's going on?  I tried signing out and signing back in again, but the same problem occurred.  I even tried re-booting.  Has something happened recently to Outlook?  Note:  There is nothing wrong with my mouse.  I am having no difficulty using it normally in other applications.
