I hate to bring brand X into the discussion, but there is a brief article there that describes the exact behavior I was experiencing with Excel. The article blames it on an alleged bug in Snow Leopard that occurs when an application is being used while Rosetta is installed. It would also explain why I was having the problem regardless of whether the file was large or small. I don't know if memory size has anything to do with it, but I have yet to have my first problem since installing the extra 2Gb of RAM. What do you forum regulars think about this?
