Vista Tutorial - internet explorer cannot open the internet site...

Just started using IE8, and getting the nag on many pages (while I am already on that page) saying IE cannot open this internet site....and if hit the return arrow to go back a page , and then reclick to the new page, it works. Whats up with that ? Am I missing some file or is this just another glitch ?
Didn't happen with IE7, and may just go back to it.

Did you try other sites ? That is a quick check to see if the problem is your browser. And it would need to be a site that uses similar setup. So if the page that doesn;'t display has lots of javascript, go to another one that has lots of javascript, etc.

On one of my sites, sometimes one particular page wouldn't display. I had to re-edit it, upload, it works fine now. So it may not be your browser. It could be that site.

its been happening on several sites, not just one. Going to do an uninstall and revert to ie7.
thx
