I have a chart that contains a simple 'button' picture to which is attached a
macro that automatically returns the user to the main worksheet. However, I
notice that when I open the workbook in 2007, the macro is no longer
attached, and has to be reassigned.

Does anyone know if this is a design feature or flaw, and what (if anything)
can be changed in the 2003 version to ensure that the macro remains available
when opened in 2007.

Many thanks
