I have a user that was recently upgraded to Windows 7. Throughout the day, every 30 minutes on average, Excel will lock up and takes several minutes until it is responsive again. I was able to see this happen once and saw that the disk was getting hammered. It was showing 150MB/s going to the hard drive.
Now I am trying to find out why this is happening and more importantly how to fix it. Anyone seen this before or know where to start looking?
