I too installed IE 8 and VISTA would abort Desktop Mgr 4.7 when getting to processing calendar entries in my Outlook. I uninstalled DM 4.7 build 50 and installed 4.7 build 59. Nada.. still aborted. Uninstalled IE 8 and rerun DM 4.7. Still bombs. Do the clean uninstall instructions which were posted in 2006 still apply? Anyone else with IE 8 and DM issues?
