Hello, so my buddy bought Minecraft today. I logged him on, entered my server's IP, and went to the server. Instantly entering the server I went into options and clicked on "full screen". After I did that HELL BROKE LOSE.

His client crashed and ever since never opened.

I updated his Java to 7 /17 or whatever [ the latest java]
I updated his Java JDK and JDE...
I updated his Graphics Card
I even disabled his Firewall....

I have been searching and searching for a fix and NOTHING, has worked... So I am here, begging for the communities assistance with this issue!!!

Here is the Error message he is getting through the client:


Minecraft has crashed!

Please help! Any information will be MUCH appreciated. Sadly I don't have his system specs but this is what I know:

He is running a dual proc @ 2.20ghz and 4gb ram.
Honestly no clue on the gfx card, 

Thanks guys!
