Microsoft Expresses Explorer 4.0a -- Microsoft has quietly released Internet Explorer 4.0a, which will also be available on the Microsoft Office 98 CD-ROM (currently in manufacturing). If you already use Explorer 4.0 there's no need to rush off to download this release, because the only changes are for compatibility with Office 98 and new installers which include Outlook Express 4.0c. If you plan to use Office 98, you'll probably find it more efficient to install Explorer 4.0a from CD-ROM than to download anywhere from 4 MB (minimum 68K install) to 24 MB (full fat binary install) via the Internet. The 128-bit security patch for Internet Explorer 4.0 works with Explorer 4.0a.

Conversely, Outlook Express 4.0c is an important update correcting a serious problem whereby email addresses stored in the address book without an associated first or last name would be cc'd on any email message. If you use Outlook Express, it's probably faster to download version 4.0c (3.3 MB) separately, rather than as part of a larger package containing Explorer 4.0a. [GD]
