For no apparent reason, several applications now give
the following error message:

'<application name> caused invalid page fault in
module SHLWAPI.DLL at 017f:70bd1c8f'

This happened with Nero Burning Rom, Norton Windoctor,
and Explorer when trying to edit the Task Bar.

Add/Remove Programs now gives the error message:
'An error occurred while Windows was working with the
Control Panel file C:\windows\system\appwiz.cpl'.
Got the same response with Control Panel Date/Time (timedate.cpl)
and Regional Settings (intl.cpl).
