It is there no matter how you call d.what.vect, correct.
IIRC, it was put there *because* it isn't clear that d.m has moved on.

I only get black for flash color as well, in 6.3-cvs. In 6.2 the middle
click to change flash color works ok (and the default is yellow). 


there haven't been big changes to d.what.vect since the 6.2 branch was
created,

http://freegis.org/cgi-bin/viewcvs.cgi/grass6/display/d.what.vect/

so this is probably similar to the d.graph color= bugs that only became
apparent when Glynn reworked the drawing libs. (??)


flash_basecolr in what.c is set to 5 [YELLOW from color.h], and that
gets passed to flash_area() and flash_line() in flash.c. This values
makes it through to R_color(flash_colr) ok, and after the line/area is
drawn R_flush() is called, but no yellow line/area... ??
