Most advice for copying a dialog was to start in Dialogs>Dialogs>All Dialogs.

Right-click on the dialog that I want to copy then select the Edit option from the context menu.

Then use the Direct Editor > Dialog view to customize it (new ID and name).  

In the install script I copied the existing AskOptions function ((found in the C:\Program Files (x86)\InstallShield\2022\Script\Isrt\src folder) and modified it to become my test AskOptionsCustom function.

When I run my project, the dialog displays no options, but does display the buttons. 

Further it is not skinned (which is bizarre because AskOptions is a skinnable dialog).

Is there a fundamental problem attempting to use the Dialog's Edit option for my purpose?

If I had used the "Clone" option instead, would I have had better success with that? BTW, the Clone option appears to be completely undocumented.

Any help will be appreciated.
