| 12 Jul 2004 | 4 | Windows server | When Ctrl-Alt-Del is sent remotely to the VNC server, causing the Logon dialog to be shown, the username and password fields may appear grayed out.

| 1 Sep 2004 | 9 | Windows server | The Control and Alt keys can become "stuck" when the Send Ctrl-Alt-Del command is used remotely. | Press and release each key a couple of times from a new viewer session, to cause the server to reset the keys' states. | Under consideration |
| 1 Sep 2004 | 10 | Windows viewer | When Fullscreen mode is selected via the F8 menu, the Windows taskbar can remain on top of the VNC viewer window. | Use the system menu (accessible via the icon at the top left
of the VNC viewer window) to enter Fullscreen mode - the bar will

More recent Windows platforms are not affected. | No workaround | Fixed in VNC Enterprise Edition 4.1.3 and VNC Free Edition 4.1 |
| 03 Dec 2004 | 13 | Windows viewer | If the VNC viewer is minimized and the Options item is then selected from the VNC viewer taskbar entry's menu, then the Options dialog is not visible on-screen and the VNC viewer appears to hang. | If Options is selected in this way, press Escape immediately, before clicking on or selecting any other window. This will close the (invisible) Options dialog and return control to the VNC viewer. | Fixed in VNC Enterprise Edition 4.1.3 and VNC Free Edition 4.1 |
