I have three computers (2 with XP and one with W2K) wherein the excel columns will jump around and move me to the end or beginning of the column list. It seems to do this on its own and randomly. Sometimes I can get back to where I was and sometimes not. Sometimes I can go for an hour without this happening and sometimes it happens right away. This phenomenon has made excel all but useless. I do move excel files from one computer to the other all the time so maybe one computer's contamination has spread to the other two. Help?
