I have been working on a new template for a few weeks, it is currently published to a SharePoint library. I attempted to preview the form Using Filler yesterday and got the "Microsoft InfoPath has stopped working" message with "APPCRASH" as the Problem Event Name. I am able to publish the form and view it using my SharePoint Library as I am using a web enabled form.
I do not have this issue on other templates, just the one I have been working on.
I spent several hours on Google and only found 1 post on this without a reply so I'm hoping you can help :)
