There is a bug in the FormListSample that causes a stack fault exception if you close the dialog with a created item control (edit, combo or date time). I'm looking at this right now.
Solution: On the CFormListCtrl::OnDestroy method, set the m_iEdit member variable to -1 after calling ShowEditor.
Meanwhile, I added some code to handle edit control resizing when the screen is rotated. The code can be found on the same location.
