excel OWC date formatting and enter event

[Narshe]

I'm using the excel object from office web components in an asp.net
webpage. I have 2 major issues.

When a user hits enter on a cell, it moves cells. That's fine, 'cause
that's how excel behaves. But I can't find a way to get it to do a line
wrap instead. Like hitting alt-enter, or ctrl-enter, or shift-enter.
Nothing works. How is this done?

When a user enters 1234-5, the text gets converted to "May/34". Is
there a way to turn the autoformat off?

Thanks.
