Updating LWJGL

LWJGL (Light Weight Java Game Library) Is an OpenGL binding for java and is used by Minecraft to render 3D, sound, and input. The latest stable version (As of writing) is 2.9.0, though Minecraft by default comes with 2.4.2.

When and Why it Should be Updated
Updating LWJGL may fix or help many common problems including:  Common continuous crash(esp. on Windows OS) Fix for Mac "cannot get JAWT interface" error. May fix some sound bugs or failures. May fix some input bugs(ie. stuck keys, ghost mouse) Possible performance increase 

It is generally recommended to update it when ever using mods as it will rule out it being a source of problems.

Manual Updating
Download the latest stable release (lwjgl-X.X.X.zip) http://lwjgl.org/download.php, then extract the .zip file using Win-Rar or 7-Zip.

Find your Scourgecraft directory: Windows:%Appdata%\.technic\scourgecraft\ Mac OSX:~/Library/Application Support/technic/scourgecraft/ Linux:~/.technic/scourgecraft/

Make sure to back-up your.technic/scourgecraft folder before proceeding!

Replace the these files in .technic/scourgecraft/bin/ with these files in lwjgl-X.X.X/jar :

 jinput.jar lwjgl.jar lwjgl_util.jar 

Next navigate to .technic/scourgecraft/bin/natives and replace the contents with all the contents of lwjgl/natives// (If using Mac make a second copy of openal.dylib. and rename it libopenal.dylib)

Alternatively Debian-like Linux systems May use the command-line:
