Yahoo email problems with links

[macx]

Win 7, Firefox, Yahoo

When I copy and paste a link into an email, everything I type after that looks like a link.
Same color blue and is underlined and I can't reformat it.

What do I have to do to stop that?

Thanks!

After you put the link in, tap ENTER once or twice & then continue. It works in gmail, should work in yahell.
