If you quit NetSurf (which takes 30 seconds when that page is up) and rerun, CPU is 50-60% with pointer over the browser window, and negligable over the pinboard. I suspect its memory allocator issue, the huge number of index entries and associated images are probably causing the heap to become extremely fragmented, slowing allocations down to a crawl. A further indication is the time it takes to close the page when all the memory is being freed. Cheers ---Dave -- ______________________________________________________________________ David J.
