FRD remembers main window size even when window is maximized. At startup main window have size of maximized window but it's state is normal. This bug occurs in Windows style. Checking "use decorated frame" results in no frame. May it should be disabled (and unchecked)?

By chance I noticed that Quaqua switches to full screen instead of maximizing window.

BTW, is showing the main window can be disabled when clipboard monitor or CAPTCHA prompt appears?
