Picking email address from contact list

Just bought Pi Cubed as it looks very interesting and useful, but am having an issue with emailing a PDF formula. From the email screen, when I try to select a contact (by pressing the "+" in the circle on the "To:" line) the contacts come up in portrait orientation only halfway up the screen but still in landscape width, so I can't easily select anything or click on any buttons.

This is on an iPod Touch 2nd gen with OS 3.1.1
