The user just got around to installing a test version of the app with some ShowMessages in the Form's OnCreate event, but nothing appeared, so it's not even getting to execute the OnCreate event.
In summary, the app hangs during Application.CreateForm(TStudioForm, StudioForm); But the OnCreate event for this form is not executed for this user. So what does this mean? What else is executing during for CreateForm procedure that could cause it to hang? How can I debug this? I have MadExcept compiled in but it doesn't activate.
