Internet Explorer 8 text highlighted by Find command (Edit menu) loses highlighting after a short time
When I use the Find command in the Edit menu of Internet Explorer 8, the text that I am looking for on a web page gets highlighted as it should but after about 5 seconds all the highlighting disappears. If I wait long enough (maybe a minute or longer) and select the Next button the highlighting MAY reappear for a while again but will eventually disappear again.
This used to NOT happen. The found text would continue to be displayed highlighted and I could move from one occurance to the next for as long as I wanted to.
What would be causing this text to lose its highlighting?
This is happening on both a Windows XP and Windows 7 fully up to date machines.
