It is legal to sell programs with bugs but it does not change my opinion that it
is a bug.

Other chess programs also have bugs.
For example Fritz always has bugs in the tablebases and chessbase cannot fix it.
I saw that Fritz5.32 did a stupid queen sacrifice against Fritz4 and lost the
game.
Fritz5.32 had mate evaluation before sacrifising the queen and only after
sacrificing the queen it saw that it is losing.

Junior has some bugs and there are some rare positions that it does stupid
tactical  mistakes.

Fixing bugs is not an easy job but I believe that it is more easy to fix the bug
of losing on time.
