This is getting to be frustrating.

I have this nice little Solitaire I made with pyGame, that works perfectly well from the command line when launched in xterm. I have been spending too much time trying (and failing) to launch it from the apps menu and have it appear in the taskbar like a regular app.

I've gone through several sources of information, such as :

- the Python/PyGtk tutorials on Teemu's blog,
- the files in the pygame Nannoid also available at Teemu's,
- a printed column about the 770 in the French Linux Magazine,
- the maemo mailing list archives, etc.

Most of them contradict one another, or at least use different syntax and options in their desktop and service files. All the combinations I've tried yield the same result : the game launches from the menu (with or without a taskbar icon), stays around for ten seconds or less, and disappears. I understand this is a sure sign of a badly configured Osso D-BUS service (whatever that is), but everyone seems to have a different way to do it - Nannoid even seems to run just fine without a service file altogether, which is just another mystery.

It doesn't make sense that it takes less time and effort to code an app than to get it to launch from a menu and keep running, does it ? Why is this so complicated and mysterious ? Is there a definitive "Howto for normal humans" available somewhere ?
TIA,
