been searching for porn Michael Jones? this is your mother. and its wrong to search for that stuff. i cant believe you would look at that filth, I TAUGHT YOU BETTER THAN THAT!

lol, j/k.

but in the newest version, 4.9.11 (or current beta) there is an option when you type for something in the search field a button on the auto-complete that allows you to clear it.

i cant remember the "official" way (besides the previous way) to clear the auto completes though, but to disable auto-complete inside of limewire completely: tools > options > view > autocompletion and untick "Enable Autocompletion of Text Fields"
