During the installation of SP2 the install stops before it is finished. The
dialog box "Windows XP Service Pack 2 Setup Wizard" is open. The text
"Finishing installation" is visible, the task bar indicates the install is
about 50% complete, and in the Details box it says "Running processes after
install."

Task manager shows the install Wizard has a "Running" status. The system
appears to be responsive. For example, the Start button still works.

Any suggestions or comments are appreciated.
