Passing selectedField Location between Stacks

[Bernard Devlin]

Thanks for the suggestion.  It was a "mouseUp" handler, so I changed it to
"mouseDown" but it didn't make any difference.

I think the issue is actually to do with moving from stack to stack:  the
selectedChunk only refers to the character numbers in a (numbered) field.  There
is no reference to a stack.  So it seems logical to me that if  one is to click
on another stack, that the selectedChunk cannot know about the stack that the
character numbers and field refer to.  This is a pity, but I have posted another
question which when solved will, I hope, provide a workaround.
