Concentration runs from the command line but not from Gnome

[HomerSimpson]

I can run concentration from a terminal as a user but not from the Gnome menu. I ran smeg to check the actual command and it is correct. I also entered in the path to concentration and it still doesn't work.

I tried to let it run in a terminal but the message flew by too fast.

1) Why won't concentration run from the gnome menu?
2) How can I debug this?

Thanks

Can you redirect the error output to a file so you can inspect it later?

I tried that but the file is never created.

I had tried

concentration >debug.txt before I posted but then saw that you were suggesting concentration 2>debug.txt but still no dice. I am not even sure where the file would have been created so I specified the path but the file is not being created.

What am I doing wrong?

Is there a way to get Gnome to log the results in /var/log/<somehwere>?

Thanks for you help!

It should just be in your $HOME directory, but maybe try an explicit path:

This is frustrating.

I copied and pasted the command "concentration 2>/var/log/debug.txt" and still no log file.

If I run that command from the terminal it says Permission Denied. My user does not have access to that directory but even if I run:

"concentration 2>/home/<user>/debug.txt" it still does not create the log file. Of course it does if I run it from the command line but not from the gnome menu.

--Update--
In desperation I just logged out of Gnome and logged in and now it works. Thanks for the help

I've got the reverse problem. Games like concentration, scramble or torrent are easily running from fluxbox. But when I try to run them from console I am getting
