Unhappy a java-swing problem...


I have a "swing" problem and i thought that
maybe someone can help me.

i wrote a program and i wanted to creat a gui to run it.
as i said i used swing for this pourpse.
i use mozilla in unix as the web browser that loads the applet.
I use jdk1.4.2.

i checked my program and it works fine as an application(the application
doesn't use Swing).
the problems begins when I try to use it as an applet.

when i click the start button, in the frame that i created, the mozilla
window is being closed and the program crashes. in the open shell I see one of these two messages:
INTERNAL ERROR on Browser End: Plugin instance index out of bounds 29248

System error?:: Success

------------------------- or ----------------------------
INTERNAL ERROR on Browser End: Pipe closed during read? State may be corrupt

System error?:: Success

[ i noticed one more strange thing:
the program runs fine as an applet in mozilla, just if i first run it as an
application from the shell.
otherwise it crashes....]

did anybody ever saw such a thing?
does anyone has any idea if this is a common problem or maybe i did something

the applet that i am using is digitally signed - maybe this is the problem?

thanks a lot.

I am not acquainted with the applets and I've just done a couple of dirty gui but is it still crashing with appletviewer? It might be easier to debug with that... but I may say crap.
