That's not the reason, S. Just checked my XP SP3 install and it's definitely running IE7. I get thumbs of all my thousands of saved Web pages, whether as ".mht" or "html", so the problem is definitely Vista specific. I did in fact come across this site and the advice therein, a couple of weeks ago when I started this search. I was recommended back here by a friend who is a genius in the UK Flight Sim arena, who was / is convinced that I will find the fix here. I have a workaround which is to take a screenie of the page I need in XP and save it in the relative folder as a JPG, but that is crazy when I've switched to Vista. I only kept XP, as Vista and / or Hewlett Packard can't / won't supply drivers
for my two photographic scanners, so I boot into XP when I have any scanning to do, but it's crazy to have to do it each time I want to see which of my saved web pages is the one I need. To give them all a descriptive name would take weeks.
Even if there's not a fix, there must be a reason why Vista has deleted this option, if that is in fact the case.
