Youtube constantly has a black background
On all our workstations (XP Professional SP3) whenever people visit youtube they get a black Background instantly and the site becomes uneusable.
The web browser is IE 8.0.6001.18027
Flash version is: 10.3.181.34
All Machines go through a proxy (Wavecrest Cyblock) but I have tried it on my machine without going through the proxy (Both IE and Chrome) and I still get the problem. I cant see what is causing the issue.
The problem only occurs in school, I dont get the black screen at home.
Can anyone clarify the situation. Has anyone else experienced it?
