Abstract
This paper deals with the projective objects in the category of all
$Z$-frames, where the latter is a common generalization of
different types of frames. The main result obtained here is that a
$Z$-frame is ${\bf E}$-projective if and only if it is stably
$Z$-continuous, for a naturally arising collection ${\bf E}$ of morphisms.
