User has Outlook 2007 on Windows XP PC and Windows Vista laptop. No problems on the PC but Outlook hangs on the laptop if you select the Contacts or Tasks tabs. Accessing the Contacts through Tools -> Address Book works fine. CPU for Outlook.exe stays at 50% or thereabouts. Using Outlook Connector to sync with Hotmail e-mail and contacts. Tried starting Outlook in safe mode but no difference. Any ideas welcomed.
