Universal Message System
Cancel Choices Fix
Version 1.1

Introduction
After noticing that version 1.8.0 of ccoa's UMS contained a bug whereby the 'Show Choices' window had difficulties with cancelled options, this fix was made. The bug was where the default window of 1-4 choices was set to branch to a 5th 'cancelled' option, that option would exit out altogether. This fix returns that capability.

Show Choices with more than 4 visible options didn't have the problem and isn't touched.
