Keep It Simple: generator problem resolved

A problem was identified with the new play mode Keep It Simple in Random Play, introduced in version 1.23.0. If an attempt was made to generate a large puzzle in this mode (either a 7x7 puzzle with the possibility of hidden sums, or an 8x8 puzzle), the generator would sometimes not finish working - it just went on whirring.

The problem has been resolved in version 1.23.1, now available in the App Store.
