When I go to ADT → Preferences → General → Appearance I get the error message:
the currently displayed page contains invalid values
Then on the main Appearance menu I see a Themes drop down menu which doesn't work. I am trying to change the overall theme of Eclipse, I was able to change the coding window with the theme plugin but that doesn't change the rest of the applications theme.
It worked for me – Fortune Jan 14 '16 at 16:47
