I have a two part query that I'm hoping someone will be able to help me with.

If I do:

  tempRect = screenBits.bounds;
  DragWindow(myWindow, myEvent->where, &tempRect);

I am limited to draging my window within the current display (not across
multiple monitors).  The same is true, if I do a SetRect for the Rect
using the screenBits.bounds members.

However, if I perform the DragWindow using the address of sreeenBits.bounds:

  DragWindow(myWindow, myEvent->where, &screenBits.bounds);

this will let me drag my window across multiple displays.  I'm curious as
to why LSC would special case the address of and not the structure members?

The next logical thing I would like to do is to open a window that spans
more than one monitor.  If I use screenBits.bounds to set the rect for
my window, I am limited to the primary display.  I have tried using
an assignment from (**GrayRgn).rgnBBox, but this again only seems to let
me size my windows portRect to the size of the primary display.

If someone could point out a better/correct way to do this, and maybe an
example, I'd appreciate it.

Thanks in advance,

Stu.
