I have a fairly large PowerPoint file, approx. 100 slides that are linked to
6 different Excel workbooks. The workbooks are updated monthly, renamed and
then I open the PowerPoint file and update the links via EditLinks, and then
save the file. When I reopen the PowerPoint file the next day, the links have
reverted back to the old Excel workbooks. I then go through all the relinking
and it works fine. This happens every month and I don't know why or how to
fix this. Any help would be appreciated.

Thanks.
