I’ve been experiencing a recurring problem with the Chrome browser that has other users pulling their hair out and switching back to Firefox. The issue is apparently an old one, in which the Chrome browser fails to render checkboxes correctly. Other users mention radio boxes are affected too.
In my quest to spin off my garden content into a separate blog, I’ve been dependent on a plugin to also port over the photo links. The Faster Insert plugin requires me to bulk select/deselect photos, and when the checkboxes disappear, that makes the task impossible. I hope that the Google team fixes this issue soon.
