How do I select which version of Scrumwise to use?
You can select whether to use the HTML5 version or the Flash version of Scrumwise on this page. The selection is local for the computer that you make it on, so do this on each computer that you access Scrumwise from.
Alternatively, you can simply uninstall Flash, and you will then automatically get the HTML5 version. It may also be enough to just disable Flash, but that depends on your browser, since we can't detect this reliably in all browsers.
To check which version of Scrumwise you're using, see here.
