HP-15C CE often freezes

I added an input routine to the Sudoku solver (https://hp-15c-simulator.de/programs/Sud...Solver.htm) and started it twice. The first run was quite normal, after a few minutes the correct result was calculated. But the second run with different data ended with a frozen “running” in the display. Only reset helped. Have you also experienced this or is it possible that my copy is defective?

Here's a few things to consider:

a. It's possible this is a battery issue. When you have programs that run for many minutes consecutively on a 15c CE (equiv to hours or even days on an original 15C), it can dramatically drain batteries, so check this first.

b. Does it behave differently in default mode than in 15.2 mode (which you mentioned)? Very unlikely, but worth checking

c. If all checking fails, post the modified program and other folks can enter it and see if the problem can be reproduced
