title: Microsoft Excel ActiveX Controls Disabled?
body: <p>I have some Excel worksheets that use ActiveX checkboxes to control certain activity.  They worked recently but today started to give errors.  I was alerted to this by a colleague, but it was still working on my computer.  I checked his version of Excel against mine and his was newer.  I noticed there were new Windows updates, so I did the update.  After I applied pending updates, it now no longer works on my computer.  I cannot check the ActiveX checkboxes any longer, and, as a part of trying to debug, it appears I cannot even add an ActiveX control to any worksheet, even a new worksheet, any more.  I get an error dialog that says, "Cannot insert object."  (I can still add form controls, just not ActiveX.)  Anyone else experiencing this after a recent update?  Any suggestions?</p>
  
  <p>Thanks,</p>
