Symptoms
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.
Cause
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.
Resolution
To resolve this behavior, use the appropriate method.

  1. Start Internet Explorer.
  2. On the Tools menu, click Internet Options.
  3. On the Content tab, click AutoComplete.
  4. Click Clear Forms, click Clear Passwords, and then click OK.

Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
