Thanks for the advice. Using \htmlimage{noantialias} did the trick. I tried all kinds of other stuff, too, such as puttting spaces (\quads) in front and back, and including a \vphantom{\Bigl|}, but neither helped - as long as I kept the \bigl| , \bigr| in the formula. Taking them out made the problem go away. It's still a bit mysterious to me.
Anyway, thanks for the advice, and I have a path forward now. Best, Ph. On Monday 01 May 2006 00:55, you wrote: > On 01/05/2006, at 3:01 PM, Philipp K.
