This upgrade fixes 3 main problems related to the HotSync Manager v3.1.1 and its interaction with some computers. These issues are: Some computers with Windows 2000 installed cannot synchronize with Palm handhelds via the infrared port. This problem is related to changes in Windows 2000 IR configuration. HotSync manager has been updated to accommodate these changes. Some computers with Windows 2000 installed may not undock properly if an older version of HotSync manager is running on the computers. On some computers, Windows may lock up if the HotSync Manager is running and the cradle is connected to the computer.
