Saved by Another Application
I have upgraded to Mavericks OSX and Numbers 3. I have two spreadsheets on my desktop that were originally produced in Numbers 2: they appear to have upgarded to Numbers 3 style etc. When I open these spreadsheets, I get a message to the effect that the sheet has been saved by another application(?) with a revert/save anyway option. Grateful for advice on how to resolve this conflict. Thanks.
