Hi,
I have a macro-enabled workbook with a worksheet, a chart sheet, and a macro that does some basic reformatting in case the chart data is changed. I placed a form control button on the chart sheet and assigned my macro to it. So far so good. The problem is when I reopen the file: the macro assignment is replaced with the generic "Button1_Click". After reassigning everything's ok once again. Needless to say, I save the file before closing it. Why is this happening?
