Ok, Ok, I get it. RTFM. LOL.

I'll d/l the newer SDK for 2.2 and have a look. It appears that the
Number Pad keyboard type doesn't have a button and requires some work
to dismiss - either a giant hidden button catching touch events
outside the number pad or overlaying a small "Done" button or similar
on the pad itself.
Or use the Numbers & Punctuation keyboard and filter out the non-numerics.
Or, I suppose I could create a custom view with my own buttons.
Thanks for the input.
Brooke
