Thanks, but now I think I've managed the second problem... thinking of your mention of it, I opened (with textEdit) the "download.back" and the "downloads.dat", and there, I found some localisations to that ghost folder... well I did erase them one by one, been very careful not to erase anything else, and, after a restart of LW, nothing happened, the folder that I had put in the garbage didn't come again to haunt my HD...
Appart of that, I still have 0% of download indicated on the window, but, I did test on a short thing or two (there is lot of short files about ufos!), and they indicate correctly, up to 100% when finished. So, what about the few still here, and not indicating anything ? I seem to remember, that they are like that since I did a restructuration of my all PC (Portable Computer) and had to copy them to reboot them... (I'm not quite shure that was or not the time I did trough MFR), but I guess that if I remove them, everything will be OK from now on.
Thanks anyway.
