I have been using since XP using Windows 10 now and Palm Desktop 6.2 with Companion Link USB Sync. Yesterday synced with iPhone removed duplicated calendar entries from the desktop. The desktop shutdown when I changed months. When I reopen all the entries that were removed were back. I ran all the Windows compatibility test no errors. Uninstalled reinstalled wiith Custom Installation without Hot Sync. Every time I change the month the desktop shut down. I can the days and the years. Any reccommendations?
