Yes. I'm actually using (the really nice) rkward, which calls the html-help
pages upon "?<something>". May this be specific to that usage ... now that
I'm looking deeper into this I find that rkward actually tells me:
Using non-linked HTML file: style sheet and hyperlinks may be incorrect
- which is what happens ... how to switch to "linked HTML file"?

I see. This was actually part of the desperate attempt to find a solution to
this wrong link target issue. I'm using a plain "\link(data.frame)" now
again.

Thanks, Joh
