Mark:
Thanks for testing this. It does give me more confidence that it’s some oddity on the student’s computer.

FYI: I have bought your book (2 of ‘em. I lost one)  and InstallerMaker (still haven’t gotten a license emailed, tho). The 3 days aren’t up, tho. Anyway, I’m looking forward to using it.

Best,
Bill

That’s the information I have.

At this point, my solution is to try to get as many folks as possible to try it on Win8, and if the problem occurs again, beg, pay, whatever to get them to provide more detailed information about their computer and its settings. I think if you have any hunches or WIn8 idiosyncrasy info that could affect this, I could explore that further, but …..

Lowering the screen resolution shows the effect, but that would show the entire window pixellated, and that isn’t what is shown on the image. Only the part that is snapshot’d shows the pixellation. It really stumps me. I’m wondering if there could be some kind of jpg difference between countries. I could understand possible font differences, but the problem is the snapshot area(s).

It’s very hard to get students to give feedback, after the assignment is over and they are onto other things. Probably also unfair to ask them to participate in debugging. So, I only ask once.

This plot is created by creating the various graphic elements (fields, boxes, lines), then a snapshot taken, and then the plot elements deleted. The plot image is then the snapshot. This was also shown as pixellated (by the student with the problem), so I think it is most likely a snapshot problem.
