Hi Rudeboy...
I am having the same problem as described above. One thumbnail keeps coming up as the default...
from the cover of another album.
This is really annoying.
I'm using Transparency as my skin.
And I tried changing the thumbnail as you specified in your reply, but the path is not there. In fact I don't see the directory for my skin in the "addon" directory in c:\Program Files (x86)\XBMC\
This is really confusing. I am using XBMC 10.1 and Transparency! v3.11.5
I even went to my music directory and found the cover that was used as the default, and physically deleted the entire directory with coverart and everything. Deleted my entire Music library in XBMC, and re-added the source. As soon as I include an artist into the library, the thumbnail comes up of the stupid album cover.
Please help, my wife is going to leave me because I am going insane trying to solve this damn this
:p
