Hi! I'm having some trouble trying to download a canvas snapshot with Internet Explorer 10.
With Firefox and Chrome, when I click the button that triggers the snapshot and then the download (I followed this tutorial ) it works fine. But when I try it with internet explorer it opens a new tab with the image information as the url:

Any ideas how to make the download work in IE?
(changing the browser is not an option because working on IE is a project specification....)

Thanks! :D

IE doesn't support downloading local data. If IE gets support for the <a download> attribute, it will work.
