nope, no compressed bitmaps are being used.

here is what I am trying:
void DrawBitmap(UInt16 bitmapID, Int16 x, Int16 y)
{
VoidHand bitmapH;
BitmapPtr bitmapP;
WinHandle newOffScreenDrawWinH;
WinHandle oldDrawWinH;
UInt16 error;
RectangleType rect, viewRect;
bitmapH = DmGet1Resource(bitmapRsc, bitmapID);
oldDrawWinH = WinGetDrawWindow();
error = 0;
//src rect
rect.topLeft.x = x;
rect.topLeft.y = y;
rect.extent.x = 158;
rect.extent.y = 111;
//target rect
viewRect.topLeft.x = 1;
viewRect.topLeft.y = 30;
viewRect.extent.x = 158;
viewRect.extent.y = 111;
if(bitmapH) {
bitmapP = MemHandleLock(bitmapH);
newOffScreenDrawWinH =
WinCreateOffscreenWindow(bitmapP->width,bitmapP->height,
screenFormat, &error);
ErrFatalDisplayIf(error, "Error offscreenwin");
}
WinSetDrawWindow (newOffScreenDrawWinH);
---this is where 3.0,3.1,3.2 crashes---
WinDrawBitmap(bitmapP, 0, 0);
WinSetDrawWindow (oldDrawWinH);
WinCopyRectangle(newOffScreenDrawWinH, oldDrawWinH, &rect, 1,
30, winPaint);
MemPtrUnlock(bitmapP);
DmReleaseResource(bitmapH);
WinDeleteWindow(newOffScreenDrawWinH,true);
}
