With Views 1.4.1 installed I upgraded to WordPress ver 3.8 which has a new admin theme look.
This new style apparently affects the Views editor which has always shown as a popup layover screen with a solid white background which covers the Views Content Template when selecting new elements to add to the template.
After WP 3.8 the Views editor layover selection screen has a transparent background and the content template's existing code shows through the Views selection layover box making it very difficult to work with.
I have tried selecting the various new WP 3.8 colour theme options to see if that would fix the problem but none worked.
Attached is a screen capture of the problem.
