Hi! My partner is a graphic artist and recently she has noticed
a minor glitch in Adobe Illustrator. In the "print dialog box" if 
"white" (i.e., no) fill or stroke is selected, the box which 
normally demonstrates various shades of "black" (i.e., fill) and 
is normally invisible when "white" is selected, is now showing 10 %
"black" even when "white" fill or stroke is chosen. As I said, this
is relatively minor as "white" or lack of fill or stroke will appear 
in the application when chosen, but because the dialog box remains 
incorrect it is annoying and sometimes confusing. Has anyone else 
encountered this problem and is there a way to correct or avoid it?
Thanx in advance for any and all suggestions!
