This seems to be that a Timer is created and enabled in
ReviewForm.InitializeComponent, however it ticks before ReviewForm.Load is
called.  The Tick calls some methods on some objects that are created in Load,
so they do not exist on the first Tick.  I do not know how MS ensures that Load
gets called first, since the Tick is asynchronous.  I guess it is just a race
condition that always works on MS.

The workaround would be to not enable the Timer until the end of the Load
