Stop auto resizing of columns. RhythmBox

I use rhythmbox as the default music player. I'm very fond of the built-in
rating function. I rate my music as I play them.
Now, all the visible columns are automatically spaced.
But as you can see in the screen shot,

if I want to rate a music 5 star, I have to move my mouse to far right
side of the screen, this action activates the scroll bar.
I tried resizing the columns. But every time a new music starts playing or
I switch to a different window, it is automatically resized as the screen
shot.
This is becoming increasingly annoying. Any Idea how I can get around this
problem?
I'm using 13.04 and I've the latest version of rhythmbox.
