We have recently started to deploy Office 2010 in sections across our school.

We have only had 1 fault reported so far and that's with data links within Excel.

Workbook 1, totals up the number of marks for each subject, Workbook 2 contains formula to insert the totals from Workbook 1. When updating the totals in Workbook 1 the formula totals will not update on some of the PCs but it will on others.

Is there some sort of setting that may be preventing this from happening?
