I just upgraded to 2.4.3 and found TreeView no longer works on the Advanced Search screen. I search, get the results in a Table view mode, click the Tree View radio button and then get a "Problem loading page" error. I then upgraded NEWA to the 1.25 release and applied the patches and tried it again, same result. I tried it with both FireFox, IE 9 and my phone - all fail.
By the way, is there anyway to default the results to TreeView output? If not, could this be configurable or at least selectable from the Search screen *before* clicking the Search button? I often use a search that shows me all the upcoming movie channels listings for the next two weeks and with lots of search results, the table format is impractical. The Treeview is perfect since it aggregates all the showings of a movie into one entry and all the times lists below it, making it much easier to sort through the results and pick the movies I want to record.
