I am using LSC 3.0 to finally begin programming on the Mac.
I have a Mac II with 2MB memory...

I am having a problem calling SetWindowPic() from LSC.

I have generated a PICT, and have a handle to the picture, as well
as a pointer to a window...

WindowPtr window2;
PicHandle myPicHandle;

SetWindowPic(window2,myPicHandle);

has no effect on the window's grafport, according to LSC's debugger.
I tried using casts to make sure the function was getting the right
types, but that did not work either....

What gives here? I know the version of LSC is a bit old, but I have not 
upgraded yet. Is this the problem?

What I am trying to do here is play around with different ways to 
save images in windows for refresh during updateevents and activateevents.

I have already managed to save the image in an offscreen PixMap, but
I was just trying out different techniques.

Does anyone know what the fastest way to restore and save pixmap data
from the screen? Would if be faster to record a PICT or use the Offscreen
techniques?

Thanks. I'm totally stumped.
