I have an applet running in firefox. yay. 
The problem I'm having is that if firefox closes, the applet doesn't close. :?
If in that tab I browse away from my webpage the applet closes fine.
Searching these forums and the net in general I have not been able to find a solution.
Does anyone have any suggestions?
Is this a weird applet issue, where there's a separate, different, function call I'm supposed to make?
Thanks.
Looks like you'll have to find the problem yourself. But first, provide some more information:
What is your applet doing? I assume you are using jME in it? Anything else you could tell us?
How do you know that your applet survives firefox?
To find the problem, you should probably start with a very basic jME applet which doesn't do anything other than start up, and gradually work your way from there to what your current applet does, and see where it fails.
providing a working example might be nice, so we could also have a look to see whats wrong with it.
Thanx for finding and answering this Hevee, I forgot all about it.
(and he's advice is good stuff, I would follow it :))
