still won't open user interface
 

Ok i am having to try again here, as i can't find anyone else to help me.
I have a G5 PPC iMac, I am running LW v 4.13.0, java version 1.5.0_06.
It sort of feels like a java issue, but i have tried everything I can think of, including:
rebooting
trashing all LW refernces and dowloading again
updating Java to this version
Trashing LW preferences
and saying forget it and having a can of beer.

please help me someone.
Thanks,
Bart
