OK Found it: url given below! Optimize performance of Photoshop (Windows) - Support Knowledgebase http://www.adobe.com/support/techdocs/12dde.htm Thanks for that: it does explain a couple of things useful. 1) PS can *only* cope with 2GB of RAM!!!!! That's influenced my decision on a new PC. I was gonna go for 3GB (3x expensive 1Gb DDR). Instead I'll stick to 2Gb (4x cheap 512mb DDR) 2) PS now handles 16-bit images. (Mmmmm ..../ my PS 5.0 still only handles 15-bit images!!!!!!!) Even loading a 16-bit TIFF and resaving it as another 16-bit TIFF has lost information!
