I had a similar problem. On MAC OS X 10.6.8 running technic launcher v1.0.1.3 I get this error message: [13:27:40] [sEVERE] 2012-08-30 13:27:40 [sEVERE] A critical error has occurred. java.lang.NullPointerException at org.lwjgl.opengl.AWTUtil.getPointerLocation(AWTUtil.java:120) at org.lwjgl.opengl.AWTUtil.getCursorPosition(AWTUtil.java:138) at org.lwjgl.opengl.MouseEventQueue.resetCursorToCenter(MouseEventQueue.java:115) at org.lwjgl.opengl.MacOSXMouseEventQueue.resetCursorToCenter(MacOSXMouseEventQueue.java:71) at org.lwjgl.opengl.MouseEventQueue.setGrabbed(MouseEventQueue.java:101) at org.lwjgl.opengl.MacOSXMouseEventQueue.setGrabbed(MacOSXMouseEventQueue.java:57) at org.lwjgl.opengl.MacOSXDisplay.grabMouse(MacOSXDisplay.java:347) at org.lwjgl.input.Mouse.setGrabbed(Mouse.java:636) ... My problem seemed to be a funky mac problem. I have dual monitors, and where I was running the launcher was on my 2550x1600 monitor, it appeared to try to reset my cursor to an invalid location and therefore encountered an exception. Going full screen or running on a different monitor (1600x900 res) fixed it for me. Hope this helps.
