Web clips and cacti

Question

I'm using web clips to monitor a few cacti graphs, but every once in a while, a web clip will will lose the image it's tracking and and just show the upper left corner of the page (this area has an image, but I think that's coincidental because the web clip is wider than the image).
Is there anyway to edit what a web clip is showing, or do I just need to delete the webclip and recreate it? I currently have 7 running, and two have shown this problem.
Failing that, is there a way, given a running web clip (or it's prefs file), to get the dimensions it uses, and then recreate the clip from the command line?
I took a look at what I think is the pref's for web clips (~/Library/Preferences/widget-com.apple.widget.web-clip.plist), and there are a number of xml plist elements in the file but they seem to be just a copy of my cookies. It also has a large binary header, which I'm not sure how to interpret. I did find what looks like dimension list/url pairs farther down, but they're wrapped in binary segments, not xml, so editing them may go badly. I'll try stopping the dashboard, editing those, and restarting it.
The other odd thing is that there are only four of the seven urls I'm tracking in that plist file. The two that have shrunk aren't listed, and neither is another one that is still running correctly.
To add to the fun, some urls seem to be missing their dimensions, and others seem to have extra. I suppose this implies the dimensions are indexed off something in the header, and their proximity to a given url in the file means nothing. Joy.
I believe this is an example of a dimension list: {{365, 443}, {620, 263}}
However, I also ran into this: {{259, 108}, {620, 235}}[{1164, 751}
Not sure what the extra pair represents.

Hi MC Ready,
Just thought perhaps you're knowledgeable enough to answer this question for me (it has to do with web clip widgets made in Safari):
I have a radio station web page, which features an area to hear live broadcast through WM (Flip4Mac on my machine). Instead of having a Safari window permanently open to that site just for listening to the radio, I thought I'd make a web clip widget, which worked just fine for more than a couple of hours. Then the feed stopped, and I thought I would launch a new instance of the web clip widget, so that I might listen again.
Alas, I can't find my widget in my widgets list at the bottom of the Dashboard screen, and I had a look at:
~/Library/Widgets, as well as
/Library/Widgets
Nowhere did I find my web clip widget. Any ideas as to where I might locate it?
Bonus question: where does the web clip widget store its streamed data? If I click on the down arrow within the widget, I can use QuickTime to save the stream downloaded so far as Source or QuickTime, but I can't find this cached stream file in my hard disk.
Many thanks.
