This like PR#7277 fails for me in MDI mode but not SDI mode.
I have tracked it down to editorsetfont (in editor.c) which does
setfont(f).  That is incorrect, as there is no current window, and there 
may be no editor windows at all.  So it was setting the font on a 
random window and the effect will be unpredictable (and hence hard to 
fix).

So the problem was introduced by the editor code in 2.0.0.
