Worksheet Command Button: Double Click and Single Click events

Hi all,

I would like to have an ActiveX command button on an Excel 2010 worksheet that functions in one way with a single click, but in a different way when double-clicked.  However, if I have defined both events, the double-click event never fires.  If I then delete the single click event, then the double click event works on a double click and nothing occurs on a single click. (So I know that both events work separately.)

Does Excel 2010 not allow you to have both events defined simultaneously?

Thanks,

Peter.
