>>> Could you try the attached patch and let me know what you observe?
Using the patch below, I get a whole bunch of numbers. I hope you do
not need the entire sequence as they scroll off screen too quickly to
read. When the scrolling stops, the screen appears as follows:
11
8
9
10
11
8
9
10
<pattern then repeats several times>
11
25
26
_
What does that mean exactly? That is, why doesn't it ever get to 12?
