Hi, I'm using confirmation note with following code: GtkWidget *note; int i; note = GTK_WIDGET(hildon_note_new_confirmation(GTK_WINDOW(uidata.app), "Message)); i = gtk_dialog_run (GTK_DIALOG (note)); gtk_widget_destroy (GTK_WIDGET (note)); When the code is in an ordinary callback function it works fine, but when it is in a function which runs in a different thread, I get following error messages: GLIB CRITICAL ** Gdk - gdk_window_set_geometry_hints: assertion 'window != NULL' failed GLIB CRITICAL ** Gdk - gdk_window_move_resize: assertion 'window != NULL' failed Xlib: unexpected async reply (sequence 0x1d35)! Any hints what's wrong? -Ari
