Yes.

How it appears onscreen (via a screen capture) is shown here:

Lovely!

The FG output using the ::Save method is shown here:

Chunky!

The most obvious indications of the problem are the smooth sides of the
plots - using ::Save they are noticeably pixelated. It reminds me of my
early postgrad days when I was writing assembly code on my pokey 8088
PC-XT with a 640x512 screen to implement Brensenham's algorithm[*]

ChrisT answered my question re: the bug fix and, since you don't see any
difference in your test when you use the Alias keyword, I guess it's
time for me to ask for an upgrade.

Thanks,
