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.
**UPDATE**
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".
**UPDATE**
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.
