Does anyone know if WPF windows are supported as popup windows in Browser enabled forms? I've attempted it, and get a threading problem. Trying to work through the treading issue, but can't tell if I'm not doing it properly, or it just can't be done. It works fine running it locally inside infopath, and raises no errors in the design checker against the server.
If its not supported, what are other people doing for custom popup boxes inside browser forms? I tried view switching, but it both looks terrible, and loses the scroll position on long forms. I need a Modal Popup window to allow additional optional data on a button click.
