Many thanks for your very prompt response.

Yesterady after I wrote my message I downloaded 3.43beta2 the zip version and
tried it. It gave exactly the same results.
Today I downloaded the exe version and tried it as well, with the same
results. I know there no differnce between the HTTrack zip and the exe
versions, but i wanted to be sure.

When HTTrack  tries to download a wma file it gives similar information to
following but without any progrss on the green progress bar:

Host: <mms://www.altafsir.com>
File: /Abdulbaset/s1.wma
Name: C:/My Web Sites/Al Tafsir/www.altafsir.com/Abdulbaset/s1.wma
ContentType:

HTTP/1.1: no
ChunkMode: no

I have noticed that it takes time before jumping to another wma.
Many thanks again.
