Thanks for the reference and apologies for the response but my friend is working away. He has tried what was suggested with no luck.
I am at a complete loss now. There are numerous references on the net about this problem and numerous suggestions to the fix all dating back to around 2009 when I guess this problem first appeared. Many reference it to a Microsoft Update.
Would it be reasonable to assume that if he upgrades to Windows 8 this would fix the problem?
