http://crunchbanglinux.org – I clicked on the date to open the calendar, moved to another month to find a date, and now I am unable to close the calendar again. Is it me, or something else?After reboot the problem dissapeared, and I could not reproduce. Sorry, it is just like a signal light in my car. (running #! Statler successfully from USB stick for some time now) (HowTos)
