My life is spreadsheets... but my computer is apparently tired of them. I am searching 13 digit ISBN #s. When I first open the spreadsheet, I can paste a ISBN in the search field and it will find it in the spread sheet like expected. But then after a few successful searches, it starts pasting the search item, wherever I was last in the spreadsheet. I can clear the search field, and the same thing happens. Meanwhile, I can type an item into the search field, and it works just fine. I am using "command v", but the same thing happens using paste from the file menu. I can reboot my computer, and then it works for awhile again... Thanks for any suggestions!
