Mark: Thanks for the closure on this issue. Your answer makes perfect sense. I had looked at the C++ source for wxListCtrl and had guessed that the platform look and feel was probably underlying this issue.
The OP had asked about the wxListCtrl wxLC_VIRTUAL | wxREPORT options in an earlier post and had gotten a test program working which involved sub-classing a MyListCtrl. Then these "pretty-print" questions came up. Seems to be lots to learn with the wxGrid "virtual" methods. Should be fun and I am sure it will lead to more questions.
