This stack dump you gave me shows that when you are in the FNFC,
keyboard events get sent to carbonTextHandler, a function of
Fl_cocoa.mm, and this is bad because FLTK does not
know the FNFC window.
So, could you, please, try and comment out line
InstallEventHandler(GetEventDispatcherTarget(), textHandler, 1, textEvents,
NULL, 0L);
of file Fl_cocoa.mm (= the last of fl_open_display) and tell me what
happens.
This will preclude character palette input, but I would like
to know what happens then for FNFC.
Thanks
