Hi folks,

a very strange problem with a program of mine - unfortunately not 
reproducible on my machine, but only on the one of the customer. The 
code is part of a (signed) applet and opens a JFrame. It simply looks as 
follows:

       frame = new JFrame("The Title");
       frame.setLocationRelativeTo(this);
       frame.setSize(800,64);
       frame.setVisible(true);

where "this" is the instance of the JApplet. Now, on my machine(s) this 
works correctly - opens a JFrame over the JApplet of the correct size. 
On the customer's machine, the JFrame remains tiny, so tiny that only 
the tile bar is visible, but nothing inside it. As the code is so 
incredibly simple, I wonder what might have been gone wrong here.

I'm running a Debian Squeeze with firefox 3.5.16 and java 6 update 29, I 
also tested on Windows XP with firefox 3.6.20 and the same java version, 
works absolutely perfect, no problem.

Not so on the customer's machine, which is also an XP (but a UK 
edition), the same version of firefox (3.6.20), and java 6 update 26 (if 
I remember correctly).

I really wonder what is going on here - I'm out of ideas how to debug or 
identify the problem. The JFrame is not touched afterwards at all, it is 
not resized, not reused etc, the above code is really the only one that 
creates and modifies it.

Hope anyone has an idea how to solve this mystery, or at least how to 
identify the cause of the problem.

Is there any specific setting of Java or the firefox I should be aware of?

Greetings,
	Thomas
