I am running VistaU SP1 and Office 2007. Quite regulary Outlook will open in safe mode, but hang on normal open. I have to fix it by running Office repair, and then it works fine for a while. Yes I have a small PST, cleaned packed whatever. I know the default is to use Word to display email in Outlook - I am thinking this is the issue. It is getting REALLY old to have to run Office repair all the time. Any other ideas?
