I'll look at the data collected so far with time as soon as= I get answer to my question-triplet :-) Just don't want to play assumptions, that's all. So here the interesting part is still that apparently it could be still par= sed (see my question #2). Thanks for taking a note on this bug! --=20 You may reply to this email to add a comment.
