After running the latest version of CCleaner 2.22.968 with all the default options checked as I did in previous versions, my Windows XP SP3 hangs. Only the mouse cursor would move around the screen. Neither the System Tray nor the Desktop Icons would respond to any click, Moreover, no response to Ctrl+Alt+Delete.
This has happened several times already.
I had to manually turn off the PC with the power switch to shut it down.
I have uninstalled this version of CCleaner and reverted back to the previous version 2.21.940. I never had a problem with this version hanging my system before, and do not have the problem now.
