>> A good place to start would be on their PC and their email client!
That's the tricky part. They have absolutely no clue as to what I'm talking about, or how to look for anything in their email client. All they know is that they use Outlook Express (Windows); Not even the version they're using.
>> A re they always accessing it from the same machine?
No. There are 3 people in the office who are also seeing the black background.
>> How did it test when you were trialling it?
Everything tested fine, but that was because the tests were coming to me.

I'm not using that template at all. Should I be?
Thank you for your reply. I'm at a loss as to how to resolve this issue.
