I use Firefox and have just checked in Internet Explorer 7. In both I can copy and paste in three ways:
1 Highlight text with mouse, right-click, choose Copy, the place cursor where I want the text and right-click to paste
2 Highlight text, press Ctrl C, then Ctrl V
3 Highlight text, use Copy from the Edit menu and Paste from the same place

All work for me in both browsers.

If you want to copy text to reply to what someone has said, the click on the Quote button under the post and it will auomatically insert the text of the whole post, and you can delete any text not relevant to your reply.

I am moving this thread to the support area for further help on the issue.
