Why does a CGXComboBoxWnd cell draw over the neighboring cells when I click into it?

We have added an attribute m_bForceInsideCell to CGXComboBoxWnd. Use this attribute to force the CGXComboBoxWnd to be drawn the same way as in OG 1.1. The attribute is FALSE by default, which will let the CGXComboBoxWnd make the combobox slightly bigger than the cell when it gets the focus, so that the text in the edit box will not be clipped any more. (You can see this in the "Base Styles"-sheet in gridapp).
