iPhone 4s - Mail icons missing at bottom of screen.

gg2013

Hi
When in Yahoo mail the icons that would normally be at the bottom of the display (Eg: Delete, Mark as unread....) are missing.

Its just displaying a blank bar where the icons would normally be.

Any ideas?

Many thanks in advance.

Panic over!

Resolved - Performed a reset, holding power and home button until Apple icon appears.
