I'm playing with heatmap of Google Maps. We have a nice demo here. In this page we have all HTML and JavaScript code necessary to show this heatmap.
If I create a local HTML web page with this code and I try to show it into IE browser, it don't show any more that a message "Internet Explorer blocked this site to avoid execute scripts or ActiveX controls on your computer" (translated from spanish, sorry for bad translation).
If I put this HTML file into my web space, work perfectly.
The question is, why and how to fix it?
