[GNC] Problems with the backspace key

[Alex]

In the last week I've updated to "Build ID: 3.2+ (2018-06-24)". It has a 
different feel than before, I'm sure I'll get to love it!

However, I'm having a small problem with the backspace key.

I've been in the habit of duplicating a transaction each week and 
changing the last two characters of the Num field by pressing the 
<backspace> key twice and entering the new text, today I was attempting 
to change the characters 19 to 20. This no longer works - pressing the 
backspace key does nothing.

I have noticed that I can change the characters if I select the text to 
be replaced and overtype the text.

I've also noticed that if I close the gnucash session and restart 
gnucash the backspace key works on the text I was trying to amend in the 
previous session.

Any clues as to what the problem could be?

I could raise this as a bug.
