Yes - on both systems

Covers are cached (for performance reason) so tracks can be located on remote machine and it will not affect performance. So is it 100% reproducible for you ?

Well, as far as I can see, we're both doing the same thing, but I'm definitely seeing this on two different systems.

Perhaps it's down to the number of Albums or where they are stored? I have 1,050 in the library, and they are all stored on a WHS 2011 system.

I'm unable to reproduce.
My steps:
- open Albums
- select any album (show tracks of that album)
- click on 'Play' button (under cover) - view switches to Now Playing view
- click back (now i'm in album detail)
- click back again (now i'm in albums)

and i can see all covers as it should.

1. start out in Album view - see all Album Art

2. Choose one (in this case Adele's 19) and start it playing.

3. Then return to the Album list. All Album Art has now disappeared - except for "19"

4. You need to leave the Album view, and then re-enter it to display the Album Art again.

This is with version 1.0.1.29 - and is happening on two Windows 8 Pro system - one running 32bit and one running 64bit versions.
