I wrote a lyrics script with python,and it worked fine. In order to prevent covering existed lyrics of current track, I defined if lyrics existed, passing getting lyrics from web and did a loop for checking if the track was changed or lyrics were cleared by hand, otherwise getting lyrics.

But I found the "refresh button" could not do anything. If I change the define, I mean always getting lyrics from web, this button still not work.

Maybe I have to know the process of "refresh button"

Thanks
