Just so as to overload you completely with information joe, I also have Internet Explorer but I just highlight the text, then click on "Edit" at the top of my screen, then under that click on "Copy".
Sometimes I've gone to the trouble of actually storing it in my records, but copying is usually enough, as long as I don't forget I've done it and then copy some other bit of text, thereby wiping the copy I just made of my DS post.
MB explained this to me I think.
