You cant give up that easy. Try this
I can't quit or I won't quit
1) Put your cursor in front of the "I" in the above thread
2) Hold down the left mouse button and drag the cursor the legnth of this thread
3) This should highlight the whole sentence
4) Then keeping your cursor the highlighted sentence, right click and a text box will apear, select (copy)
5) Move your cursor to another spot in the post and right click again, select (paste) I can't quit or I won't quit
give it another shot, I think your problem was your copying sentences and not links. There is a difference. so try it again.
