After a recent update, the norton UI is mostly black and nearly unusable

I have a problem with Norton Internet Security UI.  After a recent update, the background is mostly black (or pretty dark) and the black color masks out most of the other useful fields.  For example, I cannot see the "x" field in the top right.  If I click on its approximate location, Norton "closes," but I cannot see the "x" button itself.  This UI issue is occuring on both my desktop and laptop which both have WIndows 7 Home.

 

Anyone have any ideas?  Thank you in advance.
