This is a common problem encountered when using Internet Explorer to view these posts. The easy method to handle this, is to copy & paste into Notepad first, then from notepad to the script editor.
I used to have a link that would change the format of the posts so that it would copy properly but I've lost the link and I don't recall where on here I originally saw it. I did try to find it earlier using the search feature, but got far too many posts returned to go through them all.
