I know this has been asked already, but wasn't able to find the answer yet. I have done some basic checks to make sure my form is a browser form, but for some reason clicking on the Document Library's "Add document" button still opens the InfoPath form in a separate InfoPath instance instead of the browser. Any ideas on how to make the "New" link open in the browser? Interesting note: right after I publish, InfoPath gives me the option to open the form, and when I click that it does indeed open in the browser, so maybe this is just a problem with the document library it is published to.
