Hi,
This used to work the last time I checked..
function ReLoadForm()
{
Mscrm.ReadFormUtilities.openInSameFrame(window._etc, Xrm.Page.data.entity.getId());
}
You probably need to contain this in the 'add to queue' ribbon button but the script isn't technically supported so may stop working at any rollup..
You could also try posting a comment on Scott Durow's site (www.develop1.net). He's usually pretty keen to help with this sort of thing.
