Clear History and it will clear the TypedUrls.

To remove just the Address box, you need to clear the Registry
entries.
Make a file in Notepad out of the lines below the dashed line and call
it Nomru.reg (or similar, as long as it has .reg extension)
Copy, the lines, do not retype in case of error.
Ensure that REGEDIT4 is the first line and your mail/newsreader does
not add a space to the end of any line.
Doubleclick it to clear the Address box. (Typed Urls)

If you don't want to do this all the time, you can avoid the TypedUrls
being created by using File-Open instead of entering them in the
address box.

---------------nomru.reg below--------
REGEDIT4

[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\TypedURLs]

If you are uncomfortable editing the registry as Alan has suggested, this
little free program will do it for you:  EditURLs.
