How can I freely move JComponents in IntelliJ GUI Designer?

I have the IntelliJ-Idea Ultimate Edition but I am sure it applies in the community edition as well. I cannot freely move any components (buttons, text fields) in the JPanel. They only move to fixed places and it annoys me. Is there a way to fix that?

The process I followed is:

1. I created a new Java project.
2. I created a new package.
3. I right clicked on the new package and selected "Swing UI Designer" -> "GUI Form"
4. By default a JPanel was created.

And then tried to edit it as I explained above.
