I was in the process of reporting a different bug (which I will try again in a minute) when I tried to use the 'About Logos' menu to get the version number.
This opened a window and then gave me the beach ball :-(
Two minutes later this has spread to my entire computer ... nothing responded !
I had to reset the computer through the power button and have attached the logs..
