Often enough, when using slides with ppower4 and little vertical space, I am bothered by the fact that \pause corrupts the vertical spacing (ie it does not act as equivalent to \let\pause\relax). I must take care to put my \pause in awkward places (before \end{itemize}, e.g.) because if put after in inserts more vertical space.
Is it possible to change this ? This would be a great gain for pause.sty.
