The following code from src/plugins/contrib/NassiShneiderman/NassiView.cpp doesn't work on Mac (it works with wxGTK, but not with Carbon or Cocoa based wxWidgets - it fails both with wxWidgets 2.8 and 3.0):
#if defined(__WXMSW__) wxCursor copycursor(dnd_copy_cur_xpm); wxCursor movecursor(dnd_move_cur_xpm); wxCursor nonecursor(dnd_none_cur_xpm); #else wxIcon copycursor(dnd_copy_cur_xpm); wxIcon movecursor(dnd_move_cur_xpm); wxIcon nonecursor(dnd_none_cur_xpm); #endif
Using wxCursor instead of wxIcon worked, but I'm not sure if that's the proper solution.

Fixed in trunk.
Thank you.
