I can replicate this with any XenForo editor in 1.2. Replication steps are simple and it has currently been tested on Google Chrome for Mac. @Rho Delta do you use Mac or Windows? Go to an editor that is currently blank Type any text Highlight all of the text (click and drag or Cmd + A or Ctrl + A seem to have the same effect) Click the Add Link button in the editor Type a link Click Insert The result is that no link is applied to the text. As a work around if you end your text with a space and highlight everything except the space, then the link will add properly. Oddly, if you're editing an existing post (for example) then it works absolutely fine.
