Applet in Apple Mac OSX problem

Question

Hi all,
have developing an applet long while using WinXP platform, everthing seem ok, but when i try over Apple Mac OSX, i has a loading problem saying that init failed to load ArrayList as error message said:
ArrayIndexOutOfBound, 0...
but when i debug print out the ArrayList content and its length, i'm sure that this ArrayList is NOT NULL and its length is NOT ZERO either. what is happening here? oh, ya, this only happen in Safari, in FireFox for Mac no problem, even Camino also pass the test, why? anyone have idea about this? because i'm new to Apple Mac.
also, there is another question whereby, when i use FireFox for Mac to load the applet, the applet load seem no problem but it just can't display properly. what i mean is that in Windows platform (IE6), this applet show entire applet successfully, but when i try it in Mac, it show only a part of applet without any error, but when i try to refresh the page, applet is now successfully show, why?
lastly, when a button of an applet being click and this will bring a new window with some parameters value, its work on IE in Windows platform, why it won't work for FireFox or Safari for Mac? i see prompt out saying is security problem, is there any workout of this? thanks. to summary out of junk above:
_______________________________FireFox_____Safari_____IE
_______________________________Win | Mac_____Mac____Win
1. load applet for 1st time___________OK_|_NO_____FAIL____OK
2. refresh applet after 1st load failed___OK_|_OK_____FAIL____OK
3. when applet button click (security)___OK_|_NO_____-_______OK
p/s: all above test was using same applet with same parameter and value.
below is the sample i capture from Apple Mac just now:

i has a loading problem saying that
init failed to load ArrayList as error message
said:
ArrayIndexOutOfBound, 0...Well, post the stack trace.
but when i debug print out the ArrayList content and
its length, i'm sure that this ArrayList is NOT NULL
and its length is NOT ZERO either. You can still get an out of bounds exception with those conditions. The list could exist, its length could be N, but you're trying to dereference position N + 5, for example.
try it in Mac, it show only a part of applet without
any error, but when i try to refresh the page, applet
is now successfully show, why?My guess is that you're not calling repaint() when you should, but that's just a guess.
lastly, when a button of an applet being click and
this will bring a new window with some parameters
value, its work on IE in Windows platform, why it
won't work for FireFox or Safari for Mac? i see
prompt out saying is security problem, is there any
workout of this? thanks. to summary out of junk
above:Often you can sign applets so they can do things that unsigned applets aren't allowed to do.
Maybe you're making some kind of security mistake that Firefox and Safari are (properly) catching but IE isn't. In any event, post the error message.
