Thank you for the response.
As nehon said, it seems that there was a OpenGL apps not showing in the windows task bar.
When I reboot the computer and now there is no problem.
Anyway, jMonkeyPlatform is fantastic. I like it!!
Cool, looking forward to your trademark constructive feedback
Thanks normen! That did the trick. Do you have any idea what it was in the welcome screen that caused the errors? It would be good to know so I can avoid the pitfalls in my own games.
