Apple has released Apple Remote Desktop Admin 3.2, adding compatibility with Mac OS X 10.5 Leopard and addressing a variety of bugs and minor usage issues that cause Apple to recommend the update to all users. In particular, reliability of Copy tasks has been improved; the Open Application task now works on Intel-based client Macs; resized Control/Observe windows now retain their dimensions; it's now possible to type accented characters on European language keyboards; compatibility with third party VNC viewers and servers has been improved; screen sharing performance is improved over slower Internet connections; and overall performance has been improved with lists that contain a large number of client computers. It's available via Software Update or as a 34.6 MB download. Although I had no trouble controlling a client running version 3.1 of the Apple Remote Desktop client software, version 3.2 is also available as a 4.1 MB download. Realistically, though, there's no reason to download it in most situations; you can instead select the client computer within Apple Remote Desktop Admin, and then choose Manage > Upgrade Client Software to update to the latest.
