While I have insered my SD card (also used in mobile phone) all windows freez, meaning that I cannot move with any window, even all menus does not work, they open and immediately close themselves (e.g. start and all other related to open windows). Then if I remove the SD card it runs fine. This bug appeared even in live demo.
I used Linux Mint 16 "Petra" - Cinnamon (64-bit) - http://www.linuxmint.com/edition.php?id=144 and later on also intalled all required automatic updates.
