### 4/5 — New Bugs??

*2026-01-31, version 2.4.1*

I've enjoyed this app for years but habit recently been getting interface issues and crashes related to checkpoint save and restore and puzzle reset.

Often when saving a checkpoint, the upper right menu (that houses the checkpoint and reset commands) becomes hidden. It still works, but isn't visible.

Occasionally saving or restoring a checkpoint will terminate the application and reset the current puzzle. On restart it appears as an "in progress" puzzle but has beg fully reset to its start state.

Also often the reset command does nothing leaving the puzzle as is.

When it works this is a great sudoku app.
