I have a new problem with WINXP SP3 on a HP laptop. Although the system works perfectly on boot, once I have opened an IE8 window and then closed it, these symptoms appear
the desktop background stops updating
it is no longer possible to open any folder window using Windows Explorer (e.g. MyDocs, Control Panel, c:\Windows, etc.)
When an IE8 window is closed, it will leave the Applications window in the task manager, but the instances of iexplore.exe don't leave the Process window. If I open and close IE8 multiple times, then iexplore.exe instances will accumulate - generally more than I actually opened
Using the task manager to End Process Tree on each Iexplore.exe instance will eventually cure the symptoms. When the last iexplore.exe instance is closed, the desktop will refresh and explorer folder windows will open
The only recent change to the system was the installation of an Adobe Acrobat 9 update which required a reboot. I'm looking for ways to uninstall the update as a diagnostic measure. The system will not restore to any previous restore points. A restore point is available, but after the reload/reboot procedure, a message says that the restore was unsuccessful and that no changes were made. (This condition is not new) The system also includes Norton 360, which has had zero problems since its install months ago.
Any ideas about what is causing this or how to resolve it? Thanks in advance.
