title: VBA 438 error - Object doesn't support this property
body: <p>I have a public Excel file(and set as read only), and everything works well on my work machine(machine A).</p>
  
  <p>But when I tried to execute the VBA program via ActiveX button on another machine (machine B), Excel pop out 438 error. And when tried to check the VBA program on machine B, it shows nothing in the window (but the code does exists if I check it via machine A).</p>
  
  <p>Could anyone tell me what happened on machine B?
  Last Thurs. the VBA program can still works on machine B, but it just failed when I executed it today.
  Would any MS patch impacts this?</p>
