If I install the resources.pak from newtapwithoutsearch my hyperlinks in emails no longer open iron. I reinstalled iron and did not use newtabwithout search and all is fine again.
This has happened in the past and gone away with either a new version of newtabwithoutsearch or when new version of iron has come along.
I am sure I got the latest newtabwithoutsearch downloaded.
