It's a bug that has been fixed and will appear in the next version of Sage.

True. It is tricky because fonts are proportionally spaced.

Yes, that's possible.

No. But if you click on the left edge of output you can toggle
whether or not it is word wrapped.

I've have no clue why it would be different.

That sounds like a bug involving the internal state of the web
browser's list of cell id's.

I implemented a genuine slide show mode this summer. It took a lot of
work. But it wasn't 100% perfect, so didn't get into Sage and
massively bit rotted. Hopefully I'll have time to update it.

Thanks! By the way, there is a sage-notebook Google group, which I've
cc'd this message to.
I'm working on a patch for
