Internet Explorer 7 - back were we started from?

Last week, Microsoft released the long-awaited Internet Explorer 7, the much-anticipated update to the software giant's perennially security-challenged browser. As part of its strategy for wresting back market share from the popular Firefox browser, Microsoft has emphasized the browser's various security enhancements.

But a mere 24 hours later, the first security flaw had already surfaced—sort of. Secunia Advisory 22477 classified it as an IE7 vulnerability, but Microsoft holds that the problem—a flaw in Outlook Express that can purportedly affect many browsers, not just IE7—has been exaggerated.
