Ok, I'm stumped.  Sheesh, I can't even get a ReportMouse() to work (Workbench 
version 1.3.2 on an A500)!  Here's what I've got:

I set up a NewWindow structure for a backdrop window:

struct NewWindow BackWindowOrig = {
  0,0,                                       /* left edge, top edge */
  SCR_WIDTH,SCR_HEIGHT,                      /* width, height */
  -1, -1,                                    /* detailpen, blockpen */
  VANILLAKEY|CLOSEWINDOW       /* IDCMP flags */
    |MENUPICK|MOUSEBUTTONS|MOUSEMOVE,
    BORDERLESS|WINDOWCLOSE|REPORTMOUSE|
      SMART_REFRESH|BACKDROP, /* Window Flags */
      NULL, /* &MyGadget */ /* Gadget */
      NULL,
      (UBYTE *) NULL,
      NULL,
      NULL,
      0,0,                                          /* smallest size */
      SCR_WIDTH, SCR_HEIGHT,                        /* largest size */
      CUSTOMSCREEN
      };


Then I open up my window:

struct Window *BackWindow = NULL;
if ((BackWindow = (struct Window *) OpenWindow (&BackWindowOrig)) ==
                                                                 NULL){
       shutdown ("Unable to open up background window");
     }

JUST after that, I do this:

ReportMouse (BackWindow, FALSE);

And it fails to un-report mouse events.
If I do this:

ReportMouse (BackWindow, TRUE);

The machine gurus immediately with a memory error.  I'm using Aztec C, v
3.6 (I know, I know, get that upgrade...), Amiga 500 with 3 Meg of RAM,
Supra SCSI interface.

So, do I just need more sleep, or what?  Why can't I toggle mouse
reportage?  Thanks.
