JWM Configuration manager problem

[slapshot]

Hi everybody,

I'm playing with JWM trying to change theme. It works fine but now I'm blocked to XP theme and I cannot come back to Puppy default because I receive an error writing config file. This error is generically indicated, so I cannot have more details.

Further, now TightVnc Server cannot be able to create a display. I beleive it is a permission problems, but this is happened after my playing themes.

Someone can help me ?

Thanks
Antonio
