When you type information in a form in Internet Explorer, there may be a delay or hesitation before the insertion point appears in a text box and the text that you type is displayed. There may also be a long delay or hesitation when you move the insertion point from one box to another (the delay may be from 5 to 20 seconds).

In addition, Microsoft Outlook Express may take a long time to start.


This behavior can occur for any of the following reasons:

  • The AutoComplete history may be corrupted.
  • The Pstores.exe and associated .dll files may be corrupted or their versions may be incorrect.
  • The ProtectedStorage registry key may have incorrect parameters.


To resolve this behavior, use the appropriate method.
