Hi Hendri,

thanks for your help.
I still got a problem with the overlays. I wanted to combine it with crossing out terms from the equation, but it does not work out. I tried two variants: \pause and \onslide It seems that the \onslide command does not work together with the align-environment and the pause command is for some reason ignored. I attached a simplified example.

It seems to me that you may achieve what you are looking for by using \onslide* instead of \onslide and dropping the \rput command altogether. At least doing this modification to the example you supplied worked on my computer.
