Upgraded to a new PC with Vista Ultimate on it. Blackberry Desktop manager v4.6 takes about 5-7 minutes each time to sync with my outlook 2007 (via USB). On my old PC it took about 30 seconds. Old one was XP and Outlook 2003 with USB connection. Blackberry tech support was no help. They suggsted checking compatibility mode but I already did that. Have uninstalled and reinstalled.
