I ran into a similar problem with an upgrade last year (I believe to the
SCO Xenix 2.3 SDS). It involved a redefinition of the window attribute
set command, wattrset, which was redefined in the curses.h or tinfo.h file
to something like:

	#define wattrset w32attrset

Like you, some highlighting in one particular application disappeared. I
corrected it in the appropriate source file by undefining the define:

Perhaps someone can expound on the otherwise undocumented changes that took
place in curses.
