I agree the puzzles are way too small. You can not resize or make it full screen.
What this does, is make it very hard to identify all the pieces. The programmers
are idiots in not allowing resizing or full screen. Instead, we get a tiny window of
about 6 x 8 inches (on my 15 inch crt monitor) .. maybe it is bigger on a newermonitor (like a 16 x 9 rectangular) but not on 4 x 3 monitors)
