yes,
been there,
done that,
"Downloads.Dats" is written.

And, either NO resumed downloads with LW 2.3.3 Pro,
or, if they do resume,
they begin at 0% regardless of the previous (incompleted) file size.

lots of fun when on a dial-up, trying a 10Mg file and reaching 95% complete
only to have LW 2.3.3 go back to 0%
