No, as I've said, I don't think this is a bug, this is just IE's security settings preventing local execution. My advice would be to get a local web server running on your development machine. If you're on Windows (obviously, since you are seeing this with IE), you could install IIS or a WAMP install. You could even use node.js (http://nodejs.org) to create a local webserver. Shouldn't take more than 15 minutes to get something up and running.
Opening a web page directly from the file system will always be a hit or miss, and just isn't a reliable way to develop.
