So just as the subject of post says: If I press Atl+Shift Java freezes badly and I have to force shut down of Java. The game has no problem while interacting with anything else but as soon as I press those 2 button it crashes. Its not picking up items that causes the problem just pressing those 2 button at same time even while standing still causes the crash.
If anybody has any idea how to fix this I will be grateful for the help.
This happens with any client even the standard client.
