Double Right Click not working for mail from internet addresses

Send yourself a message from an internet address. Open the e-mail in Lotus Notes then try double right mouse click on the Body to close the e-mail. Now double right mouse click in the header area and it works. It appears to have something to do with the underlying text or field properties because if you are in the header and you double mouse click directly on the TO name then it doesn’t work either. Notice as you mouse over the text the mouse changes from the arrow to the line, so I am guess if the underlying field has a certain text format it’s preventing it from working properly? If you are in a regular internal e-mail and you mouse over the text in the body field the cursor remains an arrow, unlike when in the internet e-mail.
