slow spreadsheet using numbers
I only have four spreadsheets but one is uncomplicated but long; it has about 2400 lines. Some weeks it became very, very slow; if I click, the machine is slow to respond; if I type, the data appears 15 seconds or so later. I have read that this has been a problem with Apple for a number of years, but have they come up with any solutions? I have a Mac OS X 10.6.8, processor is 2 GHz Intel Core 2 Duo, memory is 2 GB 667 MHz DDR2 SDRAM. I have used the disk utility first aid and the problem does not seem to be there. Thanks
