If you go to the sub-sub tab ["New", "Schedules" "History"]  for anything , you cannot  re-click that link.  

Generally that's not /too/ big a deal, except for pages, such as history, that can be updating all along -- like scheduled actions, for example.

Now, you can reload browser window, but that just feels a bit... funny.  My first instinct is to re-click the sub-sub tab, since that's the tab i am actually in -- and of course i can't click through. My workaround is to click a different sub-tab and then click the History tab, but that's a pita.
