Can't copy/paste artwork
I am running iTunes 10.5.1 and running into not neccasarily an issue as much as it is an annoyance. I've been using iTunes for years, so I'm not new at this by any means. All I want to do is to copy artwork from an album that I already have artwork for and paste it to a song that doesn't have artwork. I'll give the perfect example:
I have loaded a mixtape of a friend of mines songs into iTunes. He doesn't have it in iTunes, and doesn't have artwork, so I had to upload some album artwork myself (Picky like that). Today I realized that I had missed one of the songs from that album. So I went to do like I always do, go to one song from the album that has the artwork I put on it, Right-click the artwork that shows up on the bottom left hand side of iTunes, select "Copy", then select the song that I missed that doesn't have the artwork, Right-click the blank area where the artwork should be, and select paste. Voila, it should be done. Simple as that. That's how I've always been able to solve those situations.
However, now I cannot do this. No matter what song I go to, I can right-click on the album art all I want and nothing happens. No popup that says "Copy" appears anymore. I uninstalled iTunes completely (was on the 10.5.1 beta 2 with iTunes Match) and installed the full version of 10.5.1, got the same results. Thought it might have been something I caused, so I went to a friends mac and got him to try the same thing (right-click album artwork and select copy) but he couldn't right click the artwork either. Apple Support told me that this function should still be available, is anyone else running into this issue?
Please keep in mind, that I'm not trying to get album artwork from iTunes Store. I'm just trying to copy artwork that I manually loaded into iTunes myself and cannot do so. Any feedback would be greatly appreciated.
