Oh, indeed, thanks a lot! That saves the day. I have modified wxWidgets now
to send wxEVT_LIST_ITEM_FOCUSED on LVN_ODSTATECHANGED as well and this does the
trick. Of course that wxEVT_LIST_ITEM_FOCUSED is just a dummy event that
contains no real item information but my app doesn't need that anyway. I just
need to learn about selection changes and sending wxEVT_LIST_ITEM_FOCUSED
on LVN_ODSTATECHANGED seems to serve that purpose.

Still, it's all very weird because most of the time LVN_ITEMCHANGED comes in as
well with correct item information. It's just in some very isolated cases that
iItem is -1 for LVN_ITEMCHANGED and in that case LVN_ODSTATECHANGED is sent.
So no idea what's really going on.
