Second JFrame won't display as I intend

[elnbado]

App scans for a properties file. If it cannot be found, a dialog is displayed, given user option to browse for file, or create a new one.

My issue relates to the second one. When user chooses create new one, I would to display a second JFrame containg a button and a jtextarea where the user fills in the properties. After pressing save, the frame should be closed and application to first frame.

However, the second JFrame will not display properly. It's there, but the first JFrame can be seen through this one.

I'm not sure whether I should post the topic in this topic, or in the threads topic.

My code:
