Well, Blitz cannot use unsigned variables properly. The commands will treat
numbers as unsigned, but if you try to print them using the Print command,
you will see the negative number. Performing comparisons on variables also
treats them as unsigned.
I will have a look at making the values for top, total and visible into
longwords - it should be OK, as I think the OS uses tham as longwords.

It's because you have visible set to 1. I just tried it using nothing but
the OS directly and it does the same thing, so that is not a bug in the
Blitz library.
