If I have text like this and it goes on for a while and blah and blah and blah and I want to select the "text like this" for linking, I have to have an unused line below the entire post. So picture this with post with an extra intentional line beneath it in order to select anything.
Disabling the theme makes it work again. However, it used to work before this particular build with the theme turned on. My last working WLW was about 3 or 4 updates ago.
