I am unable to copy the generated code to the clipboard.
As was discovered by board member Parry: "If you have installed Windows XP Service Pack 2, a Pop-Up blocker is installed [in Internet Explorer] as part of the pack and by default this will block active content.
When you select your cells and run HTML Maker it will create an HTML page of your image as expected, but the pop-up blocker will prevent you copying the code when you click the button to send Source to the clipboard. Simply click on the pop-up security information bar, then select Allow Blocked Content and you can now copy the HTML to the clipboard."
