Look and feel issues, can it be changed?

Hi!

I upgraded from soapUI v4.5 to v5.3 and the new GUI feels strange, as if part of window edges are missing. See screenshot below (left is v4.5, right v5.3).

If I select "Use native Look&Feel", only the window title bar changes.

Is there a way to change the L&F?

The Preferences dialog is even worse, it looks like a mix of the old and new style (the tabs titles on the left are grey/old, while the rest is new/all white, see second screenshot).

I use Java8u131 64 bit on Windows 7.

Regards,

David
