Does it happen only when you clear forms under autocomplete or doing other options also hangs the IE

Delete temp internet files, history and cookies
go to windowsupdate page and update your IE

Does it happen when you login as user or administrator or any mode ?

If clearing and updating doesnot work , repair IE and do the above again and then check clearing forms

How to Reinstall or Repair Internet Explorer and Outlook Express in Windows XP

I'd not recommend manual deletion of the index* files.  I would, however, recommend first clearing the history files and cache (in full) from browser.  This from IE 6 help
The AutoComplete feature saves previous entries you've made for Web addresses, forms, and passwords. To delete entries from the Address bar, you must clear your History folder. You cannot clear individual entries from the list of saved entries.

On the Tools menu in Internet Explorer, click Internet Options.
Click the General tab.
Under History, click Clear History.

When typing information in Web forms, and typing passwords, you can remove an item from the list of suggestions by clicking the item and then pressing the DELETE key.
For Help on an item, click  at the top of the dialog box, and then click the item.

To adjust AutoComplete settings

You can configure AutoComplete to save and suggest only the information you want. You can choose whether to use AutoComplete for Web addresses, forms, and passwords, or not use it all. You can also clear the history for any of these.

In Internet Explorer, on the Tools menu, click Internet Options.
Click the Content tab.
Under Personal information, click AutoComplete.
Select the check boxes for the AutoComplete options you want to use.


The index.dat is a hidden system file; but exists in multiple locations.   There are 3rd party products to manage them, though, again I would not choose to use these alternatives.

Here are some links, informative and helpful, in my humble opinion.
The Internet Explorer Index.dat File in the History Folder May Become Very Large


After you install Internet Explorer version 6 or version 6 Service Pack 1 (SP1) on a Windows 2000-based computer that is running Terminal Services, if the "Important URLs & Favorites and Links" Windows 2000 Group Policy is enabled, Index.dat files may not be deleted on the server when a user logs off from a Windows 2000 Terminal Services client. This problem may occur even though the "Delete cached roaming profiles" group policy is enabled. This problem does not occur in Microsoft Internet Explorer versions 5.0 and 5.01 or if the "Important URLs & Favorites and Links" Windows 2000 Group Policy is not enabled.
Cached profile folders are created but not completely deleted because three Index.dat files cannot be deleted in three different subfolders. Therefore, every time a user logs on and off, new folders are created on the computer that is running Terminal Services in the user_name, user_name.000, user_name.001 format. A new folder is created for each user. These folders quickly fill the hard disk of the computer that is running Terminal Services.
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Internet Explorer 6 service pack that contains this hotfix.

Since you do find a need to delete the index.dat file, this is important and helpful, though specific to prior IE versions:

This problem may occur because of the existence of a corrupt or damaged Internet Explorer index file.
To resolve this problem, delete the Index.dat file in Internet Explorer:
In Internet Explorer, on the Tools menu, click Internet Options.
On the General tab, under Temporary Internet files, click Delete Files.
On the Delete Files dialog box message that is displayed, click OK.
Under History, click Clear History.
On the Delete all items in your History folder? dialog box, click OK.
Quit Internet Explorer.
Log on to the computer by using the account of a user who does not experience the problem, and then open a command prompt.
Change the directory to the following path:
drive:\Documents and Settings\username\Local Settings\Temporary Internet Files\Content.IE5

Type del index.dat, and then press ENTER.
Exit the command prompt and then restart the computer.
------------->>>>  The Index.dat file is re-created the next time that you log on to the computer.

I don't have a "need" for deleting the index.dat file. I just have a need for the autocomplete
clear forms button to work. However I understand that if the button does work, what it does in essence is to clear the index.dat file. I was merely trying an alternative . I would much rather have my real problem of the Autocomplete clear form "not responding"

Thanks everyone for your suggestions. I just stumbled upon a fix.
I unchecked the forms check box. Then clicked clear forms.
Then rechecked the forms check box and all is good.
Thanks Again
