Yes, I am still listening

Pandora helps me keep my sanity at work :) But every couple of hours all of a sudden the music stops and I get the following message:


Yes, I am listening. There is no way to keep the page active. I turn on the station, minimize the window and go about my day. I have tried keeping it up and clicking into the window every so often, but without fail the question appears a few hours into the day. It is very trivial, but I wish I could just let Pandora know that yes, I will be listening to you from 8:30 am till when I go home, please don't turn off.
