I saw it only some times and can't reproduce it sistematically.
Just wandered why just for radio buttons and not for other widgets.
I'll get back if I have other hints about this issue.
How can we customize the icons for radio buttons?
We tried modifying the CSS file (business.css in our case), like this:
background-image: url( theme/business/icons/radio-selected.png );
and of course ensured to have the png files in the specified path, but radio buttons did not change.
What is the correct way?

responsible for the radio button image. Probably browser caching issue?
Try to reload and/or clear browser cache.
now we ca reproduce the problem sistematically.
The problem is not tied with Radio buttons in particular, but with any image that come from the plugin jars.
For this reason we opened a more broader question here:
