i've found that 1.2.4 also breaks "gvim" a gtk+ version
of vim. starting with a existing file gives me a small
window instead of the usual size.

i also found an other strange problem which does *not*
exists if i only install 1.2.4 (btw. the programs are
using the shared libs). *but* if i recompile my programs
with the new gtk+ installation it is there:
drag and drop from my filemanager to my application panel
does not work.. !?

here is a small example which should work with 1.2.3
but not 1.2.4: with 1.2.3 it gives me 3 buttons as
i would expect. in 1.2.4 the three buttons are *very*
narrow (no resizing for button 2 and 3 after the toplevel
is shown). the original program is was talking about
could be found at http://home.pages.de/~rasca/xap-0.7.8.tar.gz


#include <stdio.h>
#include <gtk/gtk.h>

int
main (int argc, char **argv)
{
    GtkWidget *top, *box, *btn;

    gtk_init(&argc, &argv);

    top = gtk_window_new (GTK_WINDOW_TOPLEVEL);

    box = gtk_hbox_new(TRUE, 2);
    gtk_container_add (GTK_CONTAINER(top), box);


    btn = gtk_button_new_with_label("1");
    gtk_box_pack_start (GTK_BOX(box), btn, TRUE, TRUE, 0);
    gtk_widget_show_all (top);

    btn = gtk_button_new_with_label("2");
    gtk_box_pack_start (GTK_BOX(box), btn, TRUE, TRUE, 0);

    btn = gtk_button_new_with_label("3");
    gtk_box_pack_start (GTK_BOX(box), btn, TRUE, TRUE, 0);

    gtk_widget_show_all (top);

    gtk_main ();
    return 0;
}

i'm was sure there is a better way to do it. but until
no i wasn't be able to find a good example. in testgtk.c
and in the html-docu they allways use a window to create
a pixmap and don't use the *_colormap_*() functions.
please could you fill in some example lines:

 char *pixfile = "foo.xpm";
 GtkWidget *top, *box, *btn, *pixw;
 GdkPixmap *pixmap, *pixmap_mask;
 GdkColor background;

 top = gtk_window_new (GKT_WINDOW_TOPLEVEL);
 box = gtk_hbox_new (FALSE, 4);
 gtk_conainer_add (GTK_CONTAINER(top), box);

... ??

 btn = gtk_button_new ();
 gtk_container_add (GTK_CONTAINER(btn), pixw);
 gtk_box_pack_start (GTK_BOX(box), btn, TRUE, TRUE, 2);
