Go with card if you can't guarantee placement of the window.

The "from" option renders the object into a new buffer set up just for 
the snapshot, while the older "of" syntax grabs the object's rect from 
the composite screen buffer.

LiveCode renders only the content region of a window but the window 
itself is rendered by the OS, so it has no choice but to obtain that 
image from the screen buffer.
