This tab has been recovered
I posted here a little while ago on this subject of the error message "This
tab has been recovered" with IE8 but, unfortunately there was no resolution.
I have just come across another (presumably associated) problem when viewing
planefinder.net in which the display was corrupted. I therefore installed
Mozilla Firefox and both problems have gone away.
From my small experience Firefox seems to be better than IE but Microsoft
Update wont run under Firefox so I will continue to have to run two
browsers - although I don't really want to.
