Actually I have just noticed I might have been slightly wrong there: I was resuming a file of size 2.43mb, and noticed that in the downloads section it said it was downloading a file of size 1.4mb. The finished file had the filename repeated, so it was "fiilename.mpgfilename.mpg" which was a bit odd. So I think it did resume it, but treated the remaining data it as a new download in the downloads section which was a bit confusing, and then messed up the filename at the end of it.
