when i create a link with IE11 the radetior creates only this code at the beginning and at the end of the marked text:
<span class="__telerik_marker __telerik_marker_start"></span>
We recently upgraded from 7.2.2 a few days ago and are seeing this as well in Chrome and firefox in DNN Professional 7.3.3. I can create links fine in the root portal but no parent or child portals.
We too have the same problem. Strangely, if we add some bland text at the bottom of a text, we can select it and it works. But if afterwards we change the format of the text (I tried with alignment), the link doesn't get inserted. Resetting the format doesn't solve it...
We are also having the same issue with all browsers.
We have fixed this for 7.3.3 by providing a downloadable package (7.3.4 - Telerik Update)

This will be a native fix in the forthcoming 7.3.4 release
