I grabbed IE7 as soon as it came out, so I am fairly proficient at it. I'm typing this post with it.

Try this.

>> Open Internet Options. To do so, either click Tools > Internet options from the menu bar (if the menu bar is not visible, press ALT to make it visible) or click the little gear icon near the right (on the same bar that the tabs reside) and select Internet Options from it. Either way, I O will be the bottom-most option.

>> Select Security.

>> Select Custom Level... (the button).

>> In ActiveX controls and plug-ins, run down to "Automatic prompting for ActiveX controls" and select "Enable".

>> In "Scripting", select "Enable" for "Active scripting" (the option is just underneath the header).

>> Hit OK.

>> Select Advanced.

>> Go down to Security.

>> Enable both "Allow active content from CDs to run from My Computer*" (as a convenience) and "Allow active content to run in files on My Computer*" (this is the big one).

>> You would have noticed the stars next to those options, meaning that for them to take effect you have to restart IE (not the whole PC!). Close down all instances of IE, and re-open.

>> Test the script...

>> ... and then post how well it works. (Don't post that it didn't work, okay?!!)
