I had Outlook Express open and IE open and had gone to a page from a link in an email. Once i'd finished on that page, i closed Internet Explorer with alt/f4.

It seems to happen that this error occurs intermittently. Its probably speed related on when nvda looks at the data from the current window. On XP older machines this can be longer so one assumes there is more opportunity to get some misleading data!

Note that I felt sure this had a ticket already, but could not locate it.
