I'm using Emacs 24.1, if I both set (scroll-bar-mode -1) and
(set-fringe-mode 0), then if I trying to resize the frame, the frame
will gradual getting thin.
See my question on the Stack Overflow please:
http://stackoverflow.com/questions/11373826/how-to-disable-fringe-in-emacs
So does Emacs 23.3.1 do.
Thank you, but please show a complete recipe. The Stack Overflow
question indicates that linum-mode is being used, and also it is not
clear how do you start Emacs again -- do you have the fringe-mode and
scroll-bar-mode set in your .emacs or something?
At least I cannot reproduce the problem using just what you wrote.
