* Fixed a potential security problem which could allow a logged in user to gain elevated privilegies in file transfers. This problem affected Windows 2000 systems only.
* CPU use was significantly reduced in idle periods when there are no users connected.
* Fixed a problem which resulted in wrong color rendering on "big-endian" viewers (e.g. PowerPC-based Mac viewers).
* Fixed rendering of semi-transparent mouse cursors. Previously, big black boxes could be seen instead of such cursors.
