it's an IE bug, probably caused by an update that was installed overnight -

I am using Office Outlook 2007 Professional trial edition. I use a
standard
Intel based system with Windows XP Professional which is entirely up to
date
(maybe that is my problem). My browsers are IE6 and Mozilla Firefox.

All of a sudden, like last night while I slept, Office Outlook 2007 did
something that now prevents me from following a link, by clicking on it as
incorporated in an email in the reading pane, all the way to the linked
item
on the internet. Yesterday, I could. It not says this: "The operation
has
been canceled due to restrictions in effect on this computer. Please
contact
your system administrator." Huh? Well, I am the administrator and,
therefore, I have to ask myself a question I cannot answer. Since I
can't,
can you?

Man, any help you can give me to clear this problem up will be a huge
help.
Thanks, Doug
