thanks Julie
Autosave is off, entry bar is ubckecked, Edit directly in cell i son.

The prog was created in 2010, and maintained there- the only time it goes to 2007 is when I save for the client, in which case I open the prog, save as 2007, and close again. (NOT overwriting or changing the original 2010 file).

no probs since 15th (2 days of good saves woo hoo!!), I know we had some form of update yesterday (all I see is windows needs to restart after update) which may or may have had an effect.
