Web Browser Discussion, Browser Talk - Slimjet Web Browser Online Forum

I'm currently using Maxthon but I'm looking at SlimJet as a replacement. I'm reasonably impressed so far but I can't seem to find anything which will delete lists when closed. I've set SlimJet to delete cookies etc but lists are persisted for things like the search box on this forum.

Is there a setting I'm missing to clear those as well?

I've found where I can do it manually but I'd like to clear automatically when I close the browser - is that possible?
