Same issue as above. Here is a list of things that don't work:
-updating to latest LWJGL (2.8.3)
-updating to latest recommended build (6.0.7) tekkit was also tried, using recommended build (2.1.0)
-technic 7.0.0 crashes with a method not found error, so I was not able to try it at present.
-using sun-java 1.6.0_32 instead of openJDK 1.6.0_24
any ideas where exactly I should be looking for errors, and what mod would be capable of causing this?
