Just to add to the list of failed tries.
I've tried setting focus back to input after the first typed character, with
this also:
wordInput->flags(FOCUSED);
wordInput->redraw();
again, with no result;
Can someone please tell, me is this a bug in FLTK 2.x branch, since people
who use FLTK 1.1.x seem to have no problem with this, so I can start looking
for some other possible (?) means to do this, or if it's not a bug then what
is wrong with it!?
