Options/choices at bottom of all pages are blacked out.

[John J Kennedy]

I am using OO 4.1.3 and lately find that my selection (choices e.g., save, 
discard, ect.) at the bottom of all relevant pages are “blacked out.” The only 
way that I have found to view them is to select PREFERENCES and then 
APPEARANCE.  What have I done to cause this or better, how can this problem be 
resolved??
