[GoogleCodeExporter]

What steps will reproduce the problem?
1. Load a game
2. Enter arbitrary text at prompt
3. Press backspace twice

What is the expected output or behavior?  What do you see instead?
Frotz crashes to desktop. 

What version of Frotz are you using?
1.5

What device model are you using (iPhone 3GS, iPad, iPod Touch 3rd gen,
etc.)
2nd gen iPad

What version of iOS?  3.2, 4.0, 4.3, etc.)
4.3 

Please provide any additional information below.

This first happened when attempting to quickly delete a 2 char string, so I 
assumed Frotz might be trying to delete the character at index -1, but it also 
crashes after the second backspace in longer test strings. Pressing the 
backspace key when text has never been entered oddly does NOT trigger this, but 
typing in a single character, deleting it, and then pressing backspace at the 
blank prompt will.
