if i was you I would run correct refference and see if it helps. Should solve most of your problums. Either that or sprinkle some holy water on your computer It may be possesed :) . I have been readying strange things about bum files channels becoming corupted and resaving it in photoshop seams to help. xoconostle advice was pretty good about the resizing thing consitering your computer is running a old OS and a fairly old cpu . More rams not really going to help you much till you switch to a better OS . it really cant see or use it in the right way.
