I-Tunes radio

[Chelsea]

Dear listers,
I seem to have a problem with I-Tunes 7.7. Whenever I go to listen to  
the radio through I-Tunes, I try to expand row 20 by clicking the left  
mouse button on my laptop. I have to click it a few times to expand  
that current row, but instead of expanding row 20, it expands row 18.  
Is this a problem with VO not focusing? Or is there a new trick to  
listen to the radio?
