Annoyed at Photoshop Elements

Well, not so much at Elements as at the general slowness of my computer. My version of Elements only runs on OS 9, and as the new Intel Macs don't run OS 9, I have to use my old Powerbook, which is woefully under-powered. I was helping my friend Al with the sign for his new shop, which is a 3x1 meter beast of a file - 400+ Mb. Every time I made a change I had to wait a few minutes for it to render. We played a game of chess in between changes.
