If you have ActiveX controls, Java, JavaScript, ASP or such other scripts running on your web page and you want to disable the warning that they pops up, do either of the following:

• In Microsoft Expression Web, go to the Site menu > Site Settings > Preview tab. Check the option ‘Use Microsoft Expression Development Server: For all web pages.
• In the browser go to Tools > Internet Options > Advanced tab > Choose Allow active content to run in files on My Computer/ Allow active content to run locally.
• In the browser go to Tools > Internet Options > Security tab and set the custom level. Read the questions before you check any of them. This could be risky.
