I have three user accounts on my desktop PC running Windows 8, one for each member of my family. My account is the only one that runs with Administrator permissions. When I login to my account everything works as advertised (as far as I can tell). When either of the other accounts are used. Windows 8 Explorer hangs. What happens visiually various depending on action taken. If you hover mouse over 'Show hidden icons' icon on taskbar, the Windows 8 clock is shown. If you do nothing, you could wait several minutes before the hang clears. Sometimes the desktop hang never clears. If after a minute or so, you click on the taskbar, you can cause the desktop to blank out (ie. solid color of startup background without tiles), and then reappear with the desktop icons and fences rebuilding. Another symptom is the failure and restart of Logitech Setpoint with an MS Visual C++ runtime error message. Apparently Setpoint is sensitive to a hung Explorer.
Reviewing the event log:

2013-04-02 9:54:49 PM User Logon
after the user logs on, Explorer hangs, a WER dump is performed, and as far as I can tell, Explorer restarts. SetPoint being sensitive to the Explorer hang (and I add, not the cause of the hang) fails and restarts.
To troubleshoot the problems I rebooted the PC several times, disabling services each time until I isolated the DeskScapes 8 program as the cause. With DeskScapes disabled, the is no Explorer hang, failure or restart.
