I have CVS emacs from mid June I believe -- it's been a little since I
updated -- compiled with --with-gtk, and I noticed an interesting
behavior.
If you run emacs like this and then grab the title bar as soon as it
appears and hold down the mouse button, the window won't resize.
emacs -Q --eval="(progn (sleep-for 5) (setq initial-frame-alist '((top
. 0) (left . 20) (width . 100)(height . 30))))"
I'm guessing the window manager is waiting for me to complete the drag
and drop it somewhere, but if I wait until emacs has finished the eval
the window is never resized. I noticed this because I have a not
insubstantial .emacs and happened to try to move the window right
after it appeared and it never resized.
Not really a major bug, just odd.
