Cool - thanks.

It's a recognition that no software is bug-free, and that users
(especially children) will always find a way to make a system
difficult to use. For example, children often load activities without
closing previous ones. We can educate them to not do this, but it
still happens on occasion.

The 'solution' is to quickly restart Sugar with a Ctrl+Alt+Erase. It
solves most problems, and it's faster than rebooting.
