You'll see that when you do some non-trivial operations the cursor will appear at the next visible line (this is apparently what FSF does always). After moving to the next column on the invisible line the cursor can disappear again. Apparently the redisplay code isn't sure what it means to have point in an invisible extent. I think this is just that this case that is hard to deal with if you have a redisplay engine in the way XEmacs works. However instead of trying to define what you should do if point is invisible it would be better to fix the bug that makes it get there in the first place. Jan
