This may have been reported before...
Just want to mention that if I have Sokoban YASC running,
then I cannot run Sokoban for Windows V3.
(both programs are of the latest version as of this writing)
When Sokoban for Windows V3 runs, it pops up this message:
"Sokoban is already running.
To open a new window, you must first close the existing Sokoban process."
It's better not to have conflicts like this.
