YouTube thumbnails don't show in IE 8

[chartwise]

Recently the thumbnails & adverts on YouTube do not appear.
After waiting several minutes a red cross appears as though there is no image. Using IE8

It works fine in IE7

Could anyone tell me what has gone wrong?
They appeared again for a couple of hours ago yesterday but then disappeared again.
If it is caused by a browser setting could someone please tell me how I reset it.
If I click on an empty square the videos play OK, it's just these thumbnails and also the adverts that have gone.

This is the only webpage I have had a problem with. All other site I have browsed have been OK.

All help much appreciated

IE8 may have block swf files. Check the options. Or upgrade your flash player.

They do appear intermittantly.

It just that most of the time the images just to not download.

The videos play fine.

It's a bug in IE8.

It seems that IE8 isn't the problem.

I have since found out that it was a Google Adsense/IE8 conflict problem.

Users of IE8 going to any pages that used Google Adsense code was having various problems such as this problem I had with YouTube thumbnails, also with Operation Aborted and Window Busy error messages.

This (i believe) has now all been fixed.
