Yesterday, I wrote:
>I would like to have a macro similar to \fbox, but with rounded corners.

All I got was one ``me-too''. :-(
So I continued hacking myself :-) and finally succeeded.
Although there was only one me-too, I'll post my code here, just to
contribute to comp.text.tex. This is largely borrowed from LaTeX.TeX.

By the way --- My problem with tabular was that I didn't leave vertical
mode, which is now solved by an \mbox.

%%% put this in a .sty file
\def\ovalfbox#1{%
  \mbox{% mbox leaves vertical mode!
