Hi Everyone, Just wondering if there are others out there who have had problems with Microsoft excel 2007. I have just got a new computer at work with windows vista and a nice brand new copy of office 2007. I use excel to analyse thousands of data points from a data aquisition device, and when I do a simple x vs y scatter plot, excel 2007 cannot handle this, and subsequently takes ages to respond (at least 10 mins). I got fairly annoyed so I decided to install the older version (excel 2003) and it works perfectly! I'm convinced that it is the new software problem, as vista seems to handle the 2003 excel with no problems. Having convinced my supervisor to fork out money for office 2007, I feel I should really get to the bottom of this, and not let microsoft get away with this! I understand that there will be problems with new software packages, and microsoft will probably release a service pack in a year or so, but surely excel 2007 should be able to do simple tasks!? Opinions appreciated!
