Ctrl's renamed from 2013 to 2010
 

I put some ActiveX controls in an Excel 2010 sheet and I change the
default name (e.g. "comboABC").

When I use the file with Excel 2013, all works fine. I save the file.

When I use the file in Excel 2010, I see that the controls have the
default name (e.g. "CommandButton1") and the VBA program no longer
works. If I try to rename the controls, Excel crashes.

What should I do?

Thank you
