If the application is seeing this header, then you should change it. Have a
conditional compile so the dll includes __declspec(dllexport) but the main
app does not.

There is no need for the form to have an owner. Construct with
TfrmAboutBox(0);
and no longer pass the TComponent*. This may be the source of the extra
