I have recently moved from Access 2000 running on Windows XP, to Access 2007 running on Windows 7 (64 bit). Over the past few weeks I have developed a problem with my database taking a long time to open up, sometimes taking up to three minutes, I have also noticed that when moving accross fields in table view it locks on a field for a number of seconds before moving again. My hard drive is defragmented on a weekly schedule, so I have discounted that, but having asked a number of friends no one seems to have any answers to resolve this problem. I would add that my previous experience with the older version of Access and XP was fine. Any suggestions would be most gratefully received as I am finding it very frustrating. Mike
