[Jython-users] newbie: Dispatching events pains

[Gosth <st...@ka...>]

Hi Jythoneers,

I'm experiencing some troubles with  the events dispatching in this very
first jython-test.
After the selection of the Look & Feel change and the selection of another
item in the Preferences menu , I'm not able to access the Look & Feel Menu
again.

Could anyone help me??

TIA
Stefano
