I have inherited a workbook from a previous employee that has a few
buttons that start macros when pushed. In the past, I've always been
able to right-click on a button and assign it a macro. With this
workbook, nothing happens if you right-click on the buttons (the font
on the button changes a bit, but that's it). Any idea how I can get
around this and see what macro is assigned to each button? (I'd like
to make the sheet a bit more user-friendly, and it would be much easier
if I could just re-assign the macros instead of creating a whole new
sheet.)

Thanks!
Kim
