#1 Cursor positioning problem

[Pete Chown]

Apparently when one line of ciphertext has been typed in, the cursor becomes mis-aligned. It appears one behind the last character, meaning that characters tend to get transposed.

For example, type:

AAAAA AAAAA ... AAAAA
A

At the end of this the cursor will be placed erroneously in column 1. This was reported for the Windows build -- it hasn't been checked yet for other platforms.
