>Thanks Rick, I think that will do best. Changing the registry is not as comfortable as we're talking about thousands of workstations and wan't to avoid any IT involvement.

It's in HKCU so you can actually write it as part of your application. In fact that's what I do in Help Builder/Markdown Monster.

The problem with the header is that you can only guarantee that if you control the content. Random internet content may or may not have the header and so the display might change.
