On Win7 64bit:
1: Movie is Courage Under Fire, in metaX selected genres Drama and Military & War, saved the file.
2. Close MetaX, open Movie Library
3. Select Courage Under Fire from the left pane Movie list...both genres are in the file as expected
4. MovieLibrary>Search> select Drama in genre list, no other selections. Courage Under Fire does NOT appear in the search results
5. Repeat step 4 to select Military & War genre. Same result, the movie is not found
6. Tried to select both Drama and Military & War genres to see if an exact multi-genre match is possible. Not able to select multiple genres in the search box.
So the 2 genres do appear in the MovieLibrary listings, but neither genre can be matched in the search.
