Any particular caliber ? I'm trying to duplicate what you are experiencing. Just now I have tried 35, 44, 45, they all work normally in Firefox. Ditto for the Chrome browser.
Either there is a bug unique to the caliber you are selecting, or else your browser doesn't like my program.
I've tested my site on numerous browsers, and it's always worked with the default security settings. However, it's possible to change the security settings so that my site won't work.
