email opening a webpage without asking!

[Mito]

I just received an email and upon highlighting it in Outlook Express the thing just opened a webpage!

How do I disable this? What's the right security setting?

If you have the preview pane open, some programs might be able to run from outlook(or other email programs). so if you have the preview pane on, you need to find the setting to turn it off, this should fix that problem.
