It occurs when I'm using the numeric pad (numlock off) and the alt key, although once it starts, I can make the window do flips and somersaults with the the 2nd set of cursor keys as well. These are my [custom] keyboard assignments, with alt:
72=NI,CU←
73=NI,PF←
74=NI,SM←
75=NI,PW←
76=NI,NP←
77=NI,NW←
78=NI,SU←
I can't reproduce it at will, though it's happened a few times already. If I had to guess, I'd say it's alt+pgup which gets it going, and which I've mapped to be the "previous page" function. But can't say for sure.

How bizarre. I can't reproduce it here with Xy4. I'll try with Xy3 at
home tonight.
John, what are the Xy keyboard file assignments for the keys that
cause this weird behavior?
