Please describe the problem:
When I have solved the puzzle, the high score popup screen does not appear, so I am unable to record that I have completed this particular puzzle.

I read on sourceforge tracker how another person (of the several) who had the same problem http://sourceforge.net/tracker/index.php?func=detail&aid=1651832&group_id=142841&atid=753666
shut down the program and restarted it, then re-entered the number in a spot that was already filled and then it the game completed normally.
This worked for me also - the first spot I tried (upper left corner).
I had also tried re-entering every number without first shutting down the program - that didn't work.

Steps to reproduce:
1. Roughly 3/4 of the puzzles i try have this problem when I complete the puzzle.
2. 
3. 


Actual results:


Expected results:
I expect the game to bring up the high score popup once i have completed the puzzle.

Does this happen every time?
no
