[pdftex] pdflatex or color.sty bug in environments

[ivo welch]

Hi chaps:  I have found a very strange behavior, that I believe to be 
either a bug in pdflatex (web2c 7.4.5) 3.14159-1.10b or in color.sty.  I 
am enclosing an example below.  when I use plain latex, the paragraphs 
end up black, the questions (EV) end up red---which is correct. when I 
use pdflatex, and if the questions wrap around the page below the 
paragraphs, the entire page ends up red, including the paragraphs, which 
is incorrect.

I hope this helps.   regards,  /ivo

% this works.

% this screws up.  the entire page ends up being typeset in red, 
including \onepara

\renewcommand{\onelater}[1]{\query{\txt}}

we are done.
