Not exactly sure how you do what you are doing, but normally you put the mouse-cursor at the beginning of the text you want to copy.
Then hold the left button down unitl you are at the end of the wanted text, then you press the Ctrl and C keys at the same time, go into your Word/Email program, put the cursor where you want the text, and then press Ctrl and V keys together.
For this to work, Word (and of course the email-prog) must be allowed web-access by your firewall.
