Last night I installed the latest upgrade to Lion in the expectation that the bug where large amounts of data could not be transferred to an external disk had been fixed. It hasn't! I am very annoyed by this! However, of more immediate concern to me is that my Numbers spreadsheets are no longer displaying any data. The data isn't lost because I can see the values from individual cells as I randomly click around the blank screen but while that's reassuring it's not actually any bloody use. If either of my gripes has been covered before, I apologise. I have just registered in order to have this moan and seek advice.
