How do I make iClip Lite work in newer versions of Mac OS X?
I figured out how to fix the preview!

Right click iClip lite.wdgt in Finder and select Show Package Contents, then open js/scripts.js in a text editor.

Go to line 49, which reads:

node.setAttribute("style", "position: absolute; left: 1.5em; top: 1.5em; width: 7.2em; height: 7.2em;")


Change and height to 300px and 150px, respectively. Your new line 49 should read:

node.setAttribute("style", "position: absolute; left: 1.5em; top: 1.5em; width: 300px; height: 150px;");


Save your changes, close the file, and reload the widget (in the Dashboard, click the Widget and enter ⌘R). Everything should work now.

I tested this on Mavericks and High Sierra, so I assume it will work on the full gamut of Snow Leopard through Mojave.
