1: my uncle has experience with all application saying he knows the relationship within the codes dont ask i didnt get as far as hi he can reprogram any computer as my comuter use to have xp 2: what does your game do when you figure that out youll know what "everything it usually does" is. sorry for my semi-rudeness if you found it rude i really dont know whats going on i just updated java when it happened and since then it has been doing this so no its not avg.

okay like i said before avg does nothing to anything my uncle (who is a computer tech guy) said that nothing will be affected. my problem with the shift key i dont like capitilations unless im writing a handwritten page anyways i click log in and it does everything it usually does till it is supposed to display mojang and it just closes. nothing else pops up or anything just closes

Launcher Version: latest Operating System: windows 7 premium Java Version: 7 update 5 Antivirus Program: avg but there were no problems with this before the update Description of Problem: i log in to any mod pack but it closes before it reaches the minecraft title screen Error Messages: none it just closes after log in Error Log: none
