deleting old search bars
 

does anyone know how to clear the history of any previous searches?

I would like to know the answer to this too... could someone please tell us?

LW only remembers the searches in memory (they aren't saved to the hard drive).

So, as soon as you quit LW, the searches are lost.

On startup, LW will look in the incomplete folder, and try to resume partially downloaded files from the last session (those are saved of course).

If you don't want that, go to the Library and delete the incomplete files before you quit.
