If you run the following code, you'll see the following:
1. Type something into the entry. The "bar" cursor disappears and the
text appears in the entry.
Next, you click on the button. The entry is insensitive and grayed
out.
2. Type something into the entry. The "bar" cursor disappears and the
text appears in the entry.
Next, press Enter. The default widget (the button is activated).
However, pass the mouse over the Entry. You'll notice the mouse is
permanently "vanished" from the Entry (unless you make it sensitive
again).
Is this a bug, or intended? I was quite surprised when I observed
this, wondering where one earth my mouse had gone!
It looks like this is dependent on the focus state (or mouse hiding
tricks) of the Entry when you make it insensitive.

This is the testcase:
#include <gtk/gtk.h>
GtkWidget *entry;
void
on_button_clicked(GtkWidget *widget,
gpointer data)
{
gtk_widget_set_sensitive(entry, FALSE);
}
int main(int argc, char *argv[])
{
GtkWidget *window;
GtkWidget *vbox;
GtkWidget *button;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
vbox = gtk_vbox_new(FALSE, 5);
entry = gtk_entry_new();
button = gtk_button_new_with_mnemonic("_Click Me");
gtk_container_add(GTK_CONTAINER(window), vbox);
gtk_box_pack_start(GTK_BOX(vbox), entry, FALSE, FALSE, 0);
gtk_box_pack_start(GTK_BOX(vbox), button, FALSE, FALSE, 0);
GTK_WIDGET_SET_FLAGS(button, GTK_CAN_DEFAULT);
gtk_widget_grab_default(button);
g_signal_connect(G_OBJECT(window), "destroy", gtk_main_quit, NULL);
gtk_entry_set_activates_default(GTK_ENTRY(entry), TRUE);
g_signal_connect(G_OBJECT(button), "clicked", G_CALLBACK(on_button_clicked), NULL);
gtk_widget_show_all(window);
gtk_main();
return 0;
}
