Odd. I did notice that sometimes jpeg image loading is a bit slow - white rectangles here. But they seem to load when you scroll a bit down through them. Youtube works fine here, no problems. I don't know with which assembler was mine version built, but everything seems to work. Image stuff is specific to one site only, with lot of images on one page ... Intel hardware here, so I can't confirm if it's hardware specific. -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
