I was simply playing with the GUI and for the first time i found this option to change the theme of elastix. The themes elastixblue, elastixvine everything worked fine. But once i changed it to Default theme, the GUI changed to something i totally didnt expect and i am stuck with it. The theme menu item do not show up in the Preferences and i am unable to change the theme. I have attached the screenshot of the GUI. This is how it looks like when i click the preferences menu item. Is there any way i can change the theme from command line...?? Please help.
