Good question
This is PHP app that I'm running on a WAMP platform from the Eclipse IDE, so Apache is involved.
The default browser is IE and that's what comes up when I run the app from Eclipse.
The way I finally isolated it was to view the source in IE and copy that to a file that I could run from Eclipse without any PHP.
I kept removing things till I had one form that showed the checkbox and one that didn't, the only difference being the id.
I searched all over the web and found nothing about it.
It's only the checkbox.
I tried other input types and they showed up OK.
