TightVNC is a free remote control software package derived from the popular VNC software. With TightVNC, you can see the desktop of a remote machine and control it with your local mouse and keyboard, just like you would do it sitting in the front of that computer.
TightVNC can be used to perform remote control and administration tasks in Windows, Unix and mixed network environments. It can be very helpful in distance learning and remote customer support.
TightVNC provides these features which are otherwise absent in standard VNC:
- File transfers in versions for Windows.
- Support for video mirror driver (Windows 2000 and above).
- Scaling of the remote desktop (viewer for Windows and Java viewer).
- Efficient "Tight" encoding with optional JPEG compression.
- Enhanced Web browser access.
- Support for two passwords, full-control and read-only.
# Changes in TightVNC Server:
* Fixed a bug which prevented file transfers from working properly under Windows 2000.
* Introducing new "error handler" which allows saving memory dumps on critical errors.
* In systems with swapped left and right mouse buttons, remote mouse events will be adjusted accordingly. As a result, the remote mouse should work just like the local one.
* Fixed a number of problems led to errors on setting service passwords from the installer.
* Not allowing to enter administrative passwords longer than eight characters. This limitation is caused by using standard DES-based VNC-compatible authentication. Previous versions used only the first eight characters anyway but it was possible to enter longer passwords and that could confuse users who did not know about the limitation.
* Fixed a problem with injecting lowercase characters when CapsLock was on on the server. Previous version generated uppercase characters when CapsLock was on, regardless of the Shift state.
* Implemented a special trick to bypass the problem with generating "^6" instead of "6" when using US International keyboard layout. It looks like there is a bug in Windows so we could do nothing better than to cook a workaround specifically for this case.
* Fixed clipboard handling with multiple client connections. Previously, clipboard contents might not be sent to particular clients in certain circumstances.
* Adjusted log verbosity levels for log messages generated by the control interface connection, so that such messages will not overload the log any more.
* Improved support for simple RFB clients that cannot handle desktop size changes.
* Made minor adjustments in the user interface. Specifically, the "About..." form has been cleaned up, and a typo has been corrected in the Configuration window.
# Changes in TightVNC Viewer:
* Fixed a number of problems with keyboard handling: preventing modifier keys from being stuck on switching to/from the viewer window; distinguishing left and right modifiers properly; sending arbitrary Unicode characters even if they were not defined in the original X11 protocol; and sending correct codes for the keys on the numeric keypad.
* Ctrl-Alt-Del combination should not depend on current ScrollLock state (which normally toggles Alt key to Meta key conversion).
* Fixed an issue with not sending update requests after choosing Minimize then Maximize on the viewer window (as opposed to the Minimize/Restore sequence which always worked correctly).
* Fixed a number of problems with saving and restoring connection options.
* Fixed user interface logic in the Options window. There were incorrect dependencies between compression-related controls.
* Improved phrasing for a number of error messages and log records in the file transfer module.
# Changes in the Source Code Distribution:
* Visual Studio 2010 is now supported, upgraded solution and project files are included in the source distribution. Versions for Visual Studio 2008 are included as well.
