Are there any features that will generate a list of all items downloaded
from LimeWire? I have been deleting the incompletes and have updated
my iTunes from 7.1 to 7.3 and lost many of my recent downloads due to
a bug with the new version for iPhone/iTunes.
I just need a list so I can FIND the downloads on my computer. They have
been unevenly distributed all over my hard drive and without a list to
check against my current library, I have lost over 60 downloads of varying
file types.
Any ideas or does this belong in the "suggestion" box for new features?

Try going to your LW library, right click on the column header > tick 'last modified'. Now you'll be able to sort by download date (providing the files are still in your LW library).

I don't have the newest iTunes, so I can't help you there

I don't have a right click. I am working on a G4 flat panel Mac.
Is there some other trick to reach the last modified?

Sorry, I don't use a Mac...hopefully someone else will be able to help you out there
