Tactics Trainer No Diagram

When I go to the Tactics Trainer home page, before clicking on "Start Training," I notice that, when I hover my pointer over the problem ID#, a chessboard pops up with the words "No Diagram" printed on it. In the past when I did this I saw the initial position of the problem - the pieces showed up in the pop-up diagram. This happens the same after I clear cache on my PC. How is it with other people? Maybe it's just my computer. Also I sometimes find that I think of something after leaving TT that I'd like to go back to and look at again. It would be easier to go back and find the problem if the initial position of the problem showed up in the pop-up diagram.

Aha, so it's not only me. I will report it as a bug.

Yay! The initial position is showing up again in the pop-up diagram! Great work chess dot com staff!!
