I have an Infopath xsn that i am using as the template for a SharePoint form library. I have the library set to open items in client app only because it has digital signatures that don't work in all browsers. When creating a new form from the library, it opens up in the client only and not the browser no matter what browser I am using, which is right. But when i go to open an existing form to edit, it opens up in BOTH the client form AND the browser based infopath services web app form at the same time. In IE only, it does the right thing and opens in the client only. I've seen infopath forms open in either the client or the browser, but never in both at the same time
