I'm using XP with iTune 7.6.1.9 (It is upgrading in process.)

This doesn't work after iTunes restarts , I have to close Yahoo! Widgets and open it again in order for it to start . Nice job , but like this it's pretty useless

A new version for mac and win is coming. Please wait for this update. if everything works out this should update automatically.

Also mind that this is a iTunes widget, NOT a wmp/winamp or any other program widget. I don't want to make the link between a iName and a win program, that would be rude! i Will think about creating wmpLine or something, but don't put your hopes up cause I probably won't

coming new features are a transparency theme that looks awesome with Mac OS X

I'm sorry it's taking Yahoo! so long to update this widget on their page.
I've uploaded 0.5b with them and it would have been through by now and there's a new version 0.8 which has no flaws (as far as I know) left. I have to wait for Yahoo! update this first before I can upload the new version.
for everyone who can't wait, I'm currently hosting it here too: http://pages.google.com/edit/DarkLightDusk/iLine.widget

Sometimes I'm not sure of the song that's playing in iTunes so this is a great way to always know. You can put it anywhere you want on your desktop.
