Can't find CB to remove

[Dave Jordan]

i know where this is happening, what if anything should/can i do about it?

create some callbacks so they can be removed?

Fl_Text_Buffer::remove_modify_callback(): Can't find modify CB to remove
Fl_Text_Buffer::remove_predelete_callback(): Can't find pre-delete CB to remove

the answer is 

set the buffer of the (possibly derived) widget to 0.

like this:

Some_text_editor_class->buffer(0);

Where Some_text_editor_class is either a class

derived from Fl_Text_Editor or perhaps an Fl_Text_Editor itself.
