I've tried 3.33 version, it seems ok, there is no *.tmp file, but it's not
true. Because it reports those incomplete files normal. In the final, it seems
to return to get the uncomplete files again, so if you stop the program before
that, you will get lots of incomplete files and you don't even know about it.


So the newest version is still the better, although it remains *.tmp files
besides the incomplete files, that's good for you to know there is incomplete
files, then you can d/l  them manually. 

I hope the future version can solve the problem.
