Appears to be caused by screen redraw at the same time the puzzle is being 
created. It occasionally draws a grid which is only half constructed, which can 
lead to errors.

Twofold approach to solution:
- Move code which adjusts button visibility until puzzle creation is complete - 
avoids redraw during puzzle creation
- Use synchronized lock to avoid simultaneous redraw & creation.

Can not be reproduced. Assume that it is no longer a problem anymore.
