Hello List ! since a couple of days, I have some trouble with acroread on my Squeeze amd64 box which is daily updated: fro example, when I deal two PDF files and that I play tabs, acroread gets confused and I get on shell the message: (acroread-en:12304): Gtk-CRITICAL **: gtk_widget_is_ancestor: assertion `ancestor != NULL' failed Any idea ? Thanks in advance, Jerome
