A tip: Some of my PCs I have problems found with the login. But that is less of the map as the browser. My recommendation: Private mode in the browser (CTRL + SHIFT + P) and if necessary use the ENTER key instead of the login button. For that I should deduct a star, but I moan reluctantly at a high level.
edit (Nov2013): The card is now running for a year without problems and no crashes. At the beginning, I have occasionally launched the new system but for about a 3/4 year it runs without interruption.
