lukning af vindue til nyt vindue andre parametre (threads)

System.exit betuder luk programmet, så det er ikke overraskende.

Har du prøvet at kalde dispose metoden ?

nope, hvad gør den?

public void dispose()
Releases all of the native screen resources used by this Window, its subcomponents, and all of its owned children. That is, the resources for these Components will be destroyed, any memory they consume will be returned to the OS, and they will be marked as undisplayable.

Arne du er en .... øhh... sveske :O)

Det var lige det der manglede - der kan man bare se hvad der sker, når man ikke sætter sig ind i det allermest basale Java
:O)

Her er koden hvis nogen er interesseret...
