Greetings,

I'm working on an application that, at certain times, needs to use the
whole screen, inluding the area occupied by the menu bar, and the area
outside the rounded corners of the screen's region.  

Currently, at the time I need to start using the whole screen, I set the
current port's clipRgn, and visRgn to the rect defined by the boundaries
of the the screen  ( (0,0) (640,48)  on my machine).  Then I clear the
screen, and it clears properly, but it seems as if the visRgn and/or
clipRgn is reset to its old extent, excluding the menubar and corners.
I don't manually change either region anywhere else in the code, but it
seems as if something in QuickDraw is resetting it,  unbeknownst to me.

I'm obviously missing something. Can anyone our there tell me what?

Thanx,

Jeff
