Creating a five slide powerpoint presentation and paste linking in 1 to 2 excel charts per slide. Update link (right click on chart in pp) works fine prior to saving the pp file. Once saved they are broken. The Excel file has about 100 charts spread over 20 worksheets. Think this is the root of the problem, if I create a workbook with just the charts that I need (5 charts, 1 worksheet) the same data works fine. Unfortunately I need to keep the data together for other reasons...
