It used to be, LimeWire would sometimes download a file from 2 or more users, speeding up the download by quite a bit. With the newer versions of the program, though, it never seems to do that any longer. Also, it used to be, for a file that was on multiple servers, double-clicking on the 'rating' portion of the program would expand the list, showing all the servers offering the file. That doesn't seem to happen anymore either.

What's changed? Is there an option turned off that I don't see?

Make sure the 'Grouped' box is checked under the search results.
