Outlook and Slow HTML |
| |
It's amazing how often a seemingly innocent action by the user and an
update for a program can affect negatively another. In this case, it's
MS07-027: Cumulative Security Update for Internet Explorer, released in
mid-May. After installing that update, Outlook 2003 responds very slowly
when typing HTML messages. The problem in this case is two-fold. First, users either added a large number of sites to IE's restricted zone or installed a "security" application (of the spy bot type) that added them. The cumulative security update then changed the way the Internet Explorer 7 rendering engine interacts with the Restricted Sites zone and this change causes Outlook to pause after each keystroke while the IE7 rendering engine checked the sites in the zone. The user has several options to fix this issue:
The advantages of using short restricted lists and longer safe lists is that too often the restricted address is only in use for a limited time before the webhost shuts it down. In the case of email addresses, so many spammers fake the sending address or only use them once. In either case, the software reads the list as needed, which slows down the response for the very few times it hits a valid entry. Safe lists, while long, are still much shorter than blocking every untrusted address in existence. |
