A crash will definitely occur is these 2 circumstances:
1. When the 'Hair' module is used - and you set the date for 'Second Practice' without setting the date for 'Final Practice'
or
2. When the 'Dress' module is used - and you set the 'Final Fitting Date' without setting the 'Collection Date'.
Therefore the interim solutions are either - to 'Swipe to Reset' the dates for 'Second Practice' and 'Final Fitting Date' - or respectively add the 'Final Practice Date' or 'Collection Date'
The list was appearing to fix itself because users were inadvertently adding the 'Final Practice Date' or 'Collection Date' and working round the error themselves without realising.
This will be fixed in the next update 1.4 which we submitted today.
UPDATED: we have already received reports that these steps do fix the issue of the T0-do list shutting down after a couple of seconds. A big Thank you to our user Nicky M, for her help in tracking down this problem.
