Numbers app is going grey on me !!! and freezing so can't save spreadsheets. Help !
Hi all, I'm using Numbers for the first time and every time I try to SAVE the doc (that I've entered data on) the doc goes grey and freezes !!! Infuriating as then I can't save it / assign it to a specific folder on my desktop etc. Any suggestions to cure appreciated urgent as I need to get my VAT figures in ASAP via spreadsheet, thanks in advance.
