Wow - this comment from the developer's site says it all (http://argon18.com/widgets/):

"I've heard a lot of complaints from users that the iTCM widget does not work for them... to that, all I can say is, "sucks to be you." I wrote the widget for personal use and it works just fine for me on a clean install of 10.4.6 intel updated to 10.4.10. It has also worked through various iTunes updates. I cannot "fix" the widget when i have no access to a "broken" one, so you're more than welcome to give me a mac loaded with an environment where the widget does not work."

So, uh, why bother posting it on the internet or boast that it was the "Apple Featured Download on April 29th, 2005 and featured in the September 8, 2005 Apple eNews" if you don't want to support it?
