On the advice of Andy and others I disabled the layer pre-vue images and things speeded up quite a bit. (they also mentioned this is fixed in the current CVS release) On a PIII 450, 256MB pc133 RAM, Matrox G400 32MB machine a levels adjustment on the image takes 4 seconds. 4 seconds is good but its still twice as long as photoshop. :-\ -- Jon Winters http://www.obscurasite.com/jon/ "Everybody Loves The GIMP!" http://www.gimp.org/
