Glitch between Column Browser and Now Playing

[teetersm]

After installing the latest update, I ran into a weird problem. I frequently browse my library and drag songs over to the Now Playing section while listening. I've always done this. After the update, this problem is occurring: let's say I'm browsing (alphabetically) Steely Dan albums and a Beatles song is playing. When the next song in Now Playing pops up, Dream Theater for instance, the Dream Theater song will pop up in the Steely Dan section. Simultaneously, most artists and albums disappear from the column browser. There's a quick fix. When this happens, I go to the column browser and click the top (All xxx items) and the library resets, but puts me back at the beginning, Artists beginning with A. Then I have to scroll back down to where I was. This is happening every time a new songs begins playing and it never did this before. Any ideas? Thanks in advance! ~Mark
