Description Of Issue

When I search for an artist - the discography does not list all albums by this artist. When searching for the album name itself - I then find the album by this artist. Never used to happen prior to latest 1.8 release - now happens all the time - a great pity as it wastes a lot of searching time. Also - when search for album, - sometimes shows as album - but only contains one track on that album - not the whole album - this also happens very regularly. Otherwise - enjoying all the functionality a lot - great product!. Have a great day. Luc.
