The first thing you will see is, of course, an
error window:

Historically when we have seen this error IE has closed completely, and unless
we have something like IE7Pro installed, which remembers what tabs we had open
when IE crashes and offers to open the same set, we have invariably had to use
IE's History feature to reopen the lost tabs.
With IE8, if one particular tab causes a problem, IE8 does *not* close
completely. Instead, the one problem tab is closed and reopened, and the end
user will see an alert warning that this has occurred:

One thing to bear in mind is that although IE8 does not close completely, all
open tabs will be refreshed as part of the ACR process, but the way that it
refreshes is different to normal behaviour (yes, I know, "different" is not a
very technical explanation, but I haven't worked out why I am seeing what I am
seeing).
For example, under normal conditions, if the tab which is displaying the compose
pane for my blog is refreshed I see this message:

I do *not* see the above message after an ACR - that being said, I still lose
non-saved text. Therefore, although we can describe what we are seeing as a
"refresh", that is not a true description. I will update this page as
further information becomes avaialble.
