As long as you're not keeping an active reference to the Form object, it will be garbage collected.

Probably your "back" event is being hit twice so it calls the "back" action of both the current form, and the previous form somehow.  It's hard for me to comment further without a concrete test case to look at.

You can post a video on youtube and post the link.  Also make sure to share the code you're using (and make it minimal to the test case).
