I tried to do that already- but I'm pretty sure that that option is for actually saving finished files, not Incomplete Ones. I know this because when I press "Use Default" in the same window it shows C:\Documents and Settings\User\Shared. I just can't find the option to change the default incomplete folder (C:\Program Files\LimeWire\Incomplete Files) to T:\Programs\LimeWire, where my actual limewire program is installed. Perhaps this is a bug in LimeWire.
