The courses tool is not always displaying content within a course when clicking on continue or a sidebar entry. Instead the content panel remains blank. I have had this under Beta 1 as well but I have been unable to explicitly repeat it.
When it happened again today, I click on a couple of sidebar entries ... blank.
I then used the back button (top right of panel) to return to the previous content, and then the forward button ... and the content was now there. [:)] I clicked on a couple of sidebar entries ... the content was back ... until the third click when Logos just bombed out completely, leaving me staring at my desktop!
