Thanks for the thanks and compliments, Nanook & Jack!
Nanook, here is one trick you might try: if you find a promising file with exactly the right filesize but a different filename from what you try to be resume, make a copy of your incomplete file and rename the copy to match exactly the available file (making a copy is optional but that will allow you to try resume with the original filename as well). Then just start downloading the available file and see if WinMX offers you an option to resume. I used this trick sometimes successfully with audioGnome.
