I have LimeWire 4.2.6, and was viewing a 98% complete file (that had been that way for days!). Apparently, the source finally came back on-line, and the download completed while I was viewing it. When I closed the player, there was this message about being unable to move to library; the file no longer exists! The file was deleted from "Incomplete" even though it was not copied to the shared folder. I am NOT a happy camper!
This bug really needs to be fixed. If the file had simply been left in the "Incomplete" folder, I could have taken care of moving it, myslef. I also would have been able to copy it to a CD. As it is, I have nothing to show for several days efforts at downloading the file.
A related matter is that there should be some sort of priority set for high file size and high percentage of completion, so that this situation of waiting days for the last 2% of a 442MB file does not reoccur.
