I've noticed lately that I seem to get more frequent "the file is currently in use" errors when syncing my idisk if the file has recently been opened by Office. Is this a known issue? Does Office, even if the program has quit, keep something in memory that a file is "in use" maybe for faster opening the next time? If so, how do I disable it? The error is annoying...and I worry that my changes aren't getting sync'd!
