I do lots of searches on AT and elsewhere. When I get the search results, I'll click on one link, check it out, and then "Back" to the search results. For the last week when I've done this, I now receive "Page has expired" message and "IE will not resubmit the data" .I have to enter the search again manually. Didn't use to do this. Is this a result of an IE update from MS, or did I maybe change something and not know it? I don't have this problem when using Mozilla Firebird browser (but not yet fully committed to it ).
