How to reset the default window size

Hi!

I played around with the different layouts of Adobe Connect Pro and somehow got a real chaos of window sizes and window positions when changing the resolution as well. How can I reset the layout to the default layout settings (window size, window position, which window should appear)? At this moment I cannot move a windows because it's too big to move or resize it.

Is there a possibility to undo these changes?

Thank you!

Best regards,

Thomas
