OK, we're going to need a bit more information if we're to help you with that.
First, which version of Shift did you try? Live CD or did you install it? You say "lock up", but state that your mouse can still move - sounds more like an application crash than a system crash. Did you have Compiz enabled? Did you get any video drivers (if necessary)? What are your hardware specs?
As much information you can supply will help us out here.
It happens most when I'm changing display settings, for example, changing font settings and themes. Maybe a graphics card issue but I couldn't find anything like a device manager to rectify driver issues in Shift. This was during an installed copy of Shift v0.6.2 KDE, not Live CD.
I'm not sure what Compiz is, and I'm sure this issue may be easily rectified if I bothered to research my drivers. I've been busy however, working and fixing someone's laptops... so I haven't been able to play in Shift.
My computer is old technology but I keep it running relatively smoothly. I've attached a HTML of my system information.

Mostly, when you have heard that, it's been someone with personal anecdotal evidence saying "Linux has never crashed on me". Just like someone saying "XP/Vista has never crashed on me".
No one is saying an OS will never-ever crash. Hardware problems, configuration/software mismatches or errors can cause a PC to go belly-up.
As Mr. Fish stated, the fact you can move your mouse indicates Linux (the kernel) is running, but X (the GUI) is having problems. Possibly configuration issue? When this happens, it is important to let us know what you may have done. Is this purely running as a LiveCD? Or has this been installed? Have you added or enabled any extra apps or features?
Also, when it is not running X properly, you can use CTRL+ALT+F2 to call up a command-line terminal interface and log in and troubleshoot and repair.
heheh, I know. It was more of a joke to the Linux fanboys. I realize that the issues related to crashes are numerous and never isolated to any platform.
