I'm a bit out of the loop, so please bear with me if that has been beaten to death before . For work, I'm using Photoshop CS5 64bit, CS4 for a few things as well (scanning and such), some digital capture programs from Canon and Leaf, an Epson R2400 printer, iOne color profiling hardware and software, and the usual bits and pieces for bookkeeping, email etc . My main computer is a 2008 MP, soon to be upgraded, with a dual monitor setup , running Snow Leopard . Is there anything I should be worried about when switching from Snow Leopard to Lion, could it compromise my workflow ? I've heared all those stories about lacking dual monitor support, autosave and whatnot in Lion, so I'm a litte concerned here .
