Hi Asankaf,
Are you saying it opens the form but the form is not minimized, or are you saying that the first form is not minimized but the rest are? If the latter, add some code to your InfoPath form to minimize. In general, InfoPath does not have good support for automation, so not sure what you are trying to do, but you can be sure that automating InfoPath is going to be some work. :) Good luck!
