Re: TextCtrl EVT_SET_FOCUS on Windows loses cursor

Solved my own problem: posting here in case useful for others
A bit more research took me to this thread:
https://forums.wxwidgets.org/viewtopic.php?t=43215#p176477

which indicated the importance of calling Skip() on all focus event 
handlers.

This is indeed clearly documented:
https://wxpython.org/Phoenix/docs/html/wx.FocusEvent.html

> The focus event handlers should almost invariably call wx.Event.Skip on 
their event argument to allow the default handling to take place.
