This is a very small cosmetic problem, but it bugs me: I'm preparing a background for a presentation, and I want a frame with a transparent color to appear on every slide, so I define an overlay and use metapost. I also want to frame some text elements, so I use a \framed. The problem is that in the \framed, the lines of the frame overlap at the edges, so with a transparent color, the corners are slightly darker. The minimal example below shows the problem. Any solution? Is it possible to have the frame around \framed drawn by metapost? Thanks!

Thanks so much Peter! THis looks MUCH better. The more I use metafun, the more I love it.
Hello, Did you take a look at the result with xpdf? There seems to be a problem somewhere. But it looks very nice with acroread, indeed! Cheers, Peter -- http://pmrb.free.fr/contact/
