View Full Version : Excel spreadsheets revert to manual calculation

23rd January 2009, 09:10 AM
I'm having a problem with Excel 10.
Recently it has started resetting calculation from automatic to manual.
I have tried opening a spreadsheet, then changing back to auto calculation in prefs, then saving and quitting.
When I reopen the sheet it has reverted to manual calculation.

Any help would be greatly appreciated.
