Now a really dumb question back: does gtk get a chance to do anything during the long calculations? You can check that easily by testing whether your app redraws its windows during that time. If not, then this is the culprit. If that is the case, have a look at: <http://developer.gnome.org/doc/API/2.0/gtk/gtk-General.html#gtk-main-iteration> HTH -- tomás
