At last I got it! I just download new stuff, and while downloading I deleted the stalled downloads. In the process, I canceled a file being download. I also notice before that the recent download list keeps coming back too with the stalled downloads. I guess by downloading new stuff, it helped refreshes its memory.

By the time I reopened LW, the stalled downloads are not there anymore. Whew!

I would still like to thank Lord of the Rings for his immediate concern. Thank you.
