If you navigate to Temporary Internet Folders and double-click a file-perhaps a JPG file-you get a warning that running commands on the item may be unsafe. It isn't really unsafe and, if you want to open files in Temporary Internet Folders, you can instruct IE to let you do it.

• In the Internet Explorer Menu, go to: Tools | Internet Options | Security tab.
• Click "Custom Level".
• Select the radio button labeled "Enable" under "Launching applications and files in an IFRAME".
• Click OK to close the Security dialog.
• Click OK again to apply your new selection.
