I can't say if prior versions have this issue but I do have the latest build of media centre 17.0.38 and I just realised that I am unable to save cover art that has been fetched from the internet something that always worked fine for me in media centre 16.
Just to clarify here, I can look up, view and select cover art without any issues. However the actual saving of cover art as far as I can tell seems to be a non event as the cover art view and album thumbnail stays the same as before. The same thing is happening with tv info lookup, get image does nothing. Is anyone else having this issue? Tell me it's not just something strange going on at my end!
