Hello,
I'm working with Excel 2007. I have a workbook with different sheets and
charts, with sheet tab names I all renamed. I created a sort of dashboard (on
a sheet) with my most important charts. I recorded macro's and assigned them
to buttons (drawings) on my sheets. These macro's are showing other sheets
(charts) in the same workbook.
My problem is: sometimes on opening my workbook all the charts (sheet tab
names) are renamed automatically (ex chart40), every time a higher number,
and my macro's don't work any more. I have to change the worksheet names in
my macro's.
How can I stop excel automatically renaming my worksheets?

Thanks for your help
