That utility looks great...unfortunately it doesn't work for me :(
(I use the 8.0.24 Flash player plug)
In the pandora.jar app, I get that message: "No enum const class enums.FileType.ICO"
In the Firefox window (http://localhost/) I can't see the Pandora player loading.
Then I tried to load the Pandora page in another tab of Firefox, then pressed "Grabit" and I get that message:
"HTTP/1.0 500 Internal Server Error Date: Wed May 17 23:50:21 CEST 2006 Content-Type: text/html Cache-Control: no-cache, no-store, must-revalidate, max-age=-1 Server: Pandoras Jar Connection: close"
