I started having problems this morning with Outlook 2007, loaded on Windows Vista Ultimate running as a VM in build 4560. Everything was running fine when I went to bed last night. Today, Outlook crashed several times -- including one "blue screen" total WinVista crash -- while I was using arrow keys to move through unread email in a bottom reading pane while connected to Outlook server. Any idea what may have changed overnight? Any idea of a workaround or a fix? skolnick
