After adding a movie the movie list is completely blank, and I have to use "Rebuild Movies". I'm currently using the "Date Added" sort order so that I can quickly get the fanart for the new movies, but will try it using the other sort orders as well.
Ok, it only seems to happen when the sort order is "Date Added", Modified", "Rating", and "Movie Year", and only the first time that you search for new movies or edit a movie title after opening MC. Any edits or additions work fine after I have done the "Rebuild Movies".
It also happens if I do a "Rebuild Movies" after opening MC, again only when the sort order is one of the above. Subsequent rebuilds work fine.
