Yes, they changed the behavior of S-mouse-1. It now does so-called text scaling
or resizing.


I do see that a new font is used each time I increase or decrease the text font used:

1. with my eyes (there are visible changes in the glyphs used which cannot come from scaling, particularly not in case of the used Lucida Sans Typewriter fonts)
 2. C-u x = tells me different fonts used
3. lsof reports for for the case a = 224) initial frame, b = 225) another frame opened, c = 226) text size increased, d = 227) text size reset to default and then decreased

Libris ADF Std is used for the menus from the menu bar, Vera maybe for pop-ups, and Lucida Sans Typewriter as text font in all buffers. My version of GNU Emacs 24.0.50 is elder than this month.

The question is anyway: Why are two buffers in two different frames synchronised in their appearance? Is this really a design goal? And no bug? I see this behaviour since, say, GNU Emacs 23.0.60.
