You may have some volatile functions in those files - these include NOW,
TODAY and INDIRECT. These will re-calculate whenever the file is opened, so
Excel thinks that the file has changed, even if you do nothing to the file.

Hope this helps.

When I close a couple of excel files it always asks me wheterh I want to
save, even if I have made no changes to the file (i.e. just viewed it).
Other files just close without the prompt. Is there a way to control
how/whether Excel asks you? Thx.
