Thanks et voilà! Actually I do hide LW when not using it, as with most other apps. But the changing of skins sounds wise. I thought I did notice a diff in cpu usage when it was hidden. After reopening LW I noticed (whilst hidden) it used 60 MB ram initially before 80 MB, & cpu jumped all around even up to 50% whilst fcp dropped down to 12%. This is obviously whilst the incompletes are searching out & LW is accounting for all the search results. (It certainly seemed to be a tug of war b/w lw & fcp for cpu use.) And a while later after LW settled down, without doing a search I completed one dwnld & another is dwnlding at max (for me) & somebody is uploading (back to using 20-30% [up to 49% sometimes] cpu & 118-9 MB ram. And still a tug of war b/w fcp & lw.) So cpu use hasn't improved & ram has reduced slightly, but LW is doing more than earlier.
