No problem. I'm not sure that those custom screensavers work on the Blackberry -- so check it out before plopping down that $1.99! Klaus' application should change the picture every X minutes -- X is user defined. But you can just press the space bar to rotate through the 4 or 5 pictures Klaus included. Trust me, the complicated stuff is also lots of fun. When I first tried this application I had never even heard of the JDE. I learned on the fly, and had a blast. My background is in law, investment banking, and private equity -- OK, I'm not dumb, but I ain't no IT guy either
